1.	In a parallelogram ABCD find the measure of all the angles if one of its angle is 15° less than twice the smallest angle
Answer» ANSWER: please mark as brainliest answer hope this helps you! Step-by-step explanation: All the angles are 65°, 115°, 65°, 115°. Step-by-step explanation: Let the smallest angle be 'x'. So, the other angle is 15 degrees less than twice the smallest angle. Mathematically, it is EXPRESSED as 2x-152x−15 since we know that in case of PARALLELOGRAM, opposite angles are equal. so, four angles must be x,x , 2x-15, 2x-15 We know that sum of all angles in quadrilateral is 360°. So, it becomes, \begin{gathered}x+x+2x-15+2x-15=360^\circ\\\\6x-30=360^\circ\\\\6x=360+30\\\\6x=390^\circ\\\\x=\dfrac{390}{6}\\\\x=65^\circ\end{gathered} x+x+2x−15+2x−15=360 ∘ 6x−30=360 ∘ 6x=360+30 6x=390 ∘ x= 6 390 x=65 ∘ other angle would be \begin{gathered}2x-15\\\\2(65)-15\\\\=130-15\\\\=115^\circ\end{gathered} 2x−15 2(65)−15 =130−15 =115 ∘ Hence, all the angles are 65°, 115°, 65°, 115°.

In a parallelogram ABCD find the measure of all the angles if one of its angle is 15° less than twice the smallest angle

Answer»

ANSWER:

please mark as brainliest answer

hope this helps you!

Step-by-step explanation:

All the angles are 65°, 115°, 65°, 115°.

Step-by-step explanation:

Let the smallest angle be 'x'.

So, the other angle is 15 degrees less than twice the smallest angle.

Mathematically, it is EXPRESSED as

2x-152x−15

since we know that in case of PARALLELOGRAM, opposite angles are equal.

so, four angles must be

x,x , 2x-15, 2x-15

We know that sum of all angles in quadrilateral is 360°.

So, it becomes,

\begin{gathered}x+x+2x-15+2x-15=360^\circ\\\\6x-30=360^\circ\\\\6x=360+30\\\\6x=390^\circ\\\\x=\dfrac{390}{6}\\\\x=65^\circ\end{gathered}

x+x+2x−15+2x−15=360

∘

6x−30=360

∘

6x=360+30

6x=390

∘

x=

6

390

x=65

∘

other angle would be

\begin{gathered}2x-15\\\\2(65)-15\\\\=130-15\\\\=115^\circ\end{gathered}

2x−15

2(65)−15

=130−15

=115

∘

Hence, all the angles are 65°, 115°, 65°, 115°.

2.	if the line 3 X + 4 Y = p makes a triangle of area 24 square unit with the co-ordinate Axes then find the value of p
Answer» Answer : p = ± 24 Note : • The intercept FORM of a line is given by ; x/a + y/B = 1 , where a and b are the x-intercept and y-intercept respectively . • The area of triangle formed by the line and the coordinate axes is given by ; A = ½•\|ab\| Solution : Here , The given equation of line is ; 3X + 4y = p The given equation can be rewritten as ; $= > \frac{3x}{p} + \frac{4y}{p} = 1$ $= > \frac{x}{ \frac{p}{3} } + \frac{y}{ \frac{p}{4} } = 1$ Also , The given area of the ENCLOSED triangle is 24 sq. UNITS . Thus , => ½•\| (p/3)•(p/4) \| = 24 => ½•\| p²/12 \| = 24 => \|p²\|/24 = 24 => \|p²\| = 24•24 => p² = 24•24 [ °•° \|p²\| = p² ] => p = ± √(24•24) => p = ± 24 Hence p = ± 24

2.

if the line 3 X + 4 Y = p makes a triangle of area 24 square unit with the co-ordinate Axes then find the value of p

Answer»

Answer :

p = ± 24

Note :

• The intercept FORM of a line is given by ;

x/a + y/B = 1 , where a and b are the x-intercept and y-intercept respectively .

• The area of triangle formed by the line and the coordinate axes is given by ; A = ½•|ab|

Solution :

Here ,

The given equation of line is ;

3X + 4y = p

The given equation can be rewritten as ;

$= > \frac{3x}{p} + \frac{4y}{p} = 1$

$= > \frac{x}{ \frac{p}{3} } + \frac{y}{ \frac{p}{4} } = 1$

Also ,

The given area of the ENCLOSED triangle is 24 sq. UNITS .

Thus ,

=> ½•| (p/3)•(p/4) | = 24

=> ½•| p²/12 | = 24

=> |p²|/24 = 24

=> |p²| = 24•24

=> p² = 24•24 [ °•° |p²| = p² ]

=> p = ± √(24•24)

=> p = ± 24

Hence p = ± 24

The ages of Rahul and Laxmi are in the ratio 5:7,Four years later the sum of their ages will be 56 years.What are their present ages

Answer»

Answer

Their ages will be 20 & 28 years

Explanation

Given

Ratio of the ages of Rahul and LAKSHMI is 5:7
After 7 years the SUM of their ages will be 56

To Find

Their present ages?

Solution

So as PER the ratio,

Rahul's age = 5x
Lakshmi's age = 7X

After 4 years

Rahul's age = 5x+4
Lakshmi's age = 7x+4

Sum of their ages will be 56,

➝ (5x+4) + (7x+4) = 56

➝ 5x+4+7x+4 = 56

➝ 5x+7x+4+4 = 56

➝ 12x+8 = 56

➝ 12x = 56-8

➝ 12x = 48

➝ x = 48/12

➝ x = 4

✭ Present age of Rahul

➝ 5x = 5×4 = 20 years

✭ Present age of Lakshmi

➝ 7x = 7×4 = 28 years

This kind of project-based learning helps students to secure a sustainable future. Student learning outcomes can improve as education uses intelligent management systems, learning management software, communication tools along with teaching and learning tools. 4.More weightage for assignments than external examinations Students should become the main stakeholders of the educational ecosystem and its main beneficiaries. Each student must be given unique assignments rather than common assignment for the entire class. Education should be based on the optimum usage of technological tools and resources. This means giving more weightage to Continuous Internal Evaluation (CIE 60%) and less weightage to external examination (SEE 40%) Students should be evaluated based on classroom participation, communication skills, quizzes, curricular and co-curricular activities only then students perform better. Make extra-curricular and co-curricular activities mandatory Digitalization and virtualization in education are motivating and inspiring. Pioneers of higher education must ensure that their foundations are COMPUTERIZED, open the doors for effective teaching-learning and have a high level of commitment and agility.

To change learning habits, we need to have new smart learning skills. This will enable us to educate students to create change.

Introduce the syllabus which provides student centric learning facility with ICT which prepare our students to meet the demands of the present technology.

3.Practical, Problem, Project-based learning

Education should be realistic and accommodate for practical learning. This kind of project-based learning helps students to secure a sustainable future. Student learning outcomes can improve as education uses intelligent management systems, learning management software, communication tools along with teaching and learning tools.

4.More weightage for assignments than external examinations

Students should become the main stakeholders of the educational ecosystem and its main beneficiaries.

Each student must be given unique assignments rather than common assignment for the entire class. Education should be based on the optimum usage of technological tools and resources.

This means giving more weightage to Continuous Internal Evaluation (CIE 60%) and less weightage to external examination (SEE 40%)

Students should be evaluated based on classroom participation, communication skills, quizzes, curricular and co-curricular activities only then students perform better.

Make extra-curricular and co-curricular activities mandatory

Digitalization and virtualization in education are motivating and inspiring. Pioneers of higher education must ensure that their foundations are COMPUTERIZED, open the doors for effective teaching-learning and have a high level of commitment and agility.

Write each of the following equation in ax +by+c=0 form. X/3+y/2=0

Answer»

Answer:

(i) 2, 3, -4.37

(ii) 5, -3, -4

(iii) 2, -1, 0

Step-by-step explanation:

Writing in the FORM of ax+by+c = 0.

(i)2x + 3y = 4.37

=> 2x + 3y - 4.37 = 0

Here, we have,

a = 2

b = 3

c = -4.37

(ii) 4 = 5X - 3y

=> 5x - 3y = 4

=> 5x - 3y - 4 = 0

Here, we have,

a = 5

b = -3

c = -4

(iii) 2x = y

=> 2x - y = 0

=> 2x - y + 0 = 0

Here, we have,

a = 2

b = -1

c = 0
