1.	If line segment AB measures approximately 8.6 units and is considered the base of parallelogram ABCD, what is the approximate corresponding height of the parallelogram? Round to the nearest tenth.
Answer» Answer: 4.8 units Step-by-step explanation: In the given figure side AB = 8.6 Coordinates of A(1, 3), B(8, 8), C(12, 5) and D(5, 0) Now in the given triangle we will find the ANGLE between Ab and AD to find the length of AE which is the length of the given parallelogram. $\rule {300}{1.5}$ tanθ = $\sf\dfrac{m(AB)-m(AD)}{1+m(AB)m(AD)}$ Slope m(AB) = $\sf\dfrac{8-3}{8-1}=\dfrac{5}{7}$ Slope m(AD) = $\sf\dfrac{3-0}{1-5}=-\dfrac{3}{4}$ So ; tanθ = $\sf\dfrac{\dfrac{5}{7}-(-\dfrac{3}{4})}{1+(\dfrac{5}{7})(-\dfrac{3}{4} )}$ tanθ = $\sf\dfrac{41}{13}=3.154$ θ = $\sf\:tan^{-1}(3.154)=72.41$ ° $\rule {300}{1.5}$ Now in right angle triangle ABE sin72.41° = $\sf\dfrac{DE}{5}$ 0.95324 = $\sf\dfrac{DE}{5}$ DE = 5×4.7662 = 4.8 units

If line segment AB measures approximately 8.6 units and is considered the base of parallelogram ABCD, what is the approximate corresponding height of the parallelogram? Round to the nearest tenth.

Answer»

Answer:

4.8 units

Step-by-step explanation:

In the given figure side AB = 8.6

Coordinates of A(1, 3), B(8, 8), C(12, 5) and D(5, 0)

Now in the given triangle we will find the ANGLE between Ab and AD to find the length of AE which is the length of the given parallelogram.

$\rule {300}{1.5}$

tanθ = $\sf\dfrac{m(AB)-m(AD)}{1+m(AB)m(AD)}$

Slope m(AB) = $\sf\dfrac{8-3}{8-1}=\dfrac{5}{7}$

Slope m(AD) = $\sf\dfrac{3-0}{1-5}=-\dfrac{3}{4}$

So ; tanθ = $\sf\dfrac{\dfrac{5}{7}-(-\dfrac{3}{4})}{1+(\dfrac{5}{7})(-\dfrac{3}{4} )}$

tanθ = $\sf\dfrac{41}{13}=3.154$

θ = $\sf\:tan^{-1}(3.154)=72.41$ °

$\rule {300}{1.5}$

Now in right angle triangle ABE

sin72.41° = $\sf\dfrac{DE}{5}$

0.95324 = $\sf\dfrac{DE}{5}$

DE = 5×4.7662 = 4.8 units

10.

Prove that √5 is a irrational no.

Answer»

Step-by-step explanation:

lets assume ROOT 5 is rational ...

rand rational number cn be PRESENT in p/q form

so

ROOT5=p/q

squaring both side

root5^2=p^2/q^2

5=p^2/q^2

p^2in factor of 5

q^2is factor of 5

then

5=ak(any constant)

squaring

5^2=a^2k^

25=a^2k^2

25 is factor of a

25 is factor of k

hence our assumption was wrong root5 is irrational

16.

A=b=30,sin(a+b)=sina cosb +cosa +sinb

Answer»

ANSWER:

here is your answer

Step-by-step explanation:

given angle a and angle b are EQUAL to 30°

consider,

L.H.S

SIN(30°+30°) = sin60° = √3/2

R.H.S

(sin30°)( COS 30°) + (cos30°)( sin30°)

1/2 * √3/2 + √3/2* 1/2

√3/4+√3/4

√3/2

therefore

sin(a+b) = Sin a cos b + cos a sin b

23.

The sides of a rectangle are in the ratio 3 : 7 and its area is 1029 m². Find the dimensions of the rectangle, and then find its perimeter.

Answer»

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The Perimeter of the Rectangle is 140 m.

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

GIVEN :

Ratio of the Rectangle sides = 3 : 7

Area of the Rectangle = 1029 m²

To Find :

The dimensions and Perimeter of the Rectangle

Solution :

Consider the Breadth as 3X

Consider the Length as 7x

★ $\purple{\boxed{\sf{\pink{Area = Length \times Breadth}}}}$

$\tt{\implies} \: 1029 = 7x \times 3x$

$\tt{\implies} \: 21x^{2} = 1029$

$\tt{\implies} \: x = \dfrac{1029}{21}$

$\tt{\implies} \: x = \sqrt{49}$

$\tt{\implies} \: x = 7$

$\rule{300}{1.5}$

★ Value of 3x

$\tt{\implies} \: 7 \times 3$

$\tt{\implies} \: 21$

★ Value of 7x

$\tt{\implies} \: 7 \times 7$

$\tt{\implies} \: 49$

Breadth = 21 m

Length = 49 m

$\rule{300}{1.5}$

Perimeter of Rectangle can be FOUND as the dimensions are given.

★ $\purple{\boxed{\sf{\pink{Perimeter = 2(Breadth+Length)}}}}$

$\tt{\implies} \: 2(21 + 49)$

$\tt{\implies} \: 42+ 98$

$\tt{\implies} \:140$

$\therefore$ The Perimeter of the Rectangle is 140 m.

2% of the population of a small town died due to an epidemic. a panic set in during which 14% of the remaining population left the town. if the population is then reduced to 2107 what was the original population of the town

Answer»

Let the original population be 'X'

x - (2% of x + 14% of ((100-2)% of x))= 2107

x-((2÷100)x+(14÷100)((98÷100)x))=2107

x-((2x÷100)+(7÷50)(98x÷100))=2107

x-((x÷50)+(7÷50)(49x÷50))=2107

x-((x÷50)+(343x÷2500))=2107

x-((50x÷2500)+(343x÷2500))=2107

x-((50x+343x)÷2500)=2107

x-(393x÷2500)=2107

(2500x-393x)÷2500=2107

2107x÷2500=2107

2107x=2107×2500

x=(2107×2500)÷2107

x=2500

Therefore Original population of town was 2,500.

the angle of depression of two ships from the top of light house are 45° and 30° towards east if the ships are 200m apart,find the height of the light house

Answer»

Answer:

LET A and B be given ships OC

be the LIGHTHOUSE

let hight of lighthouse = OC = H

in triangle OAC we have

tan 45 = OC/OA

so OA = H ....(i)

in triangle OBC

tan 30 = OC/OB

1/root 3=H / OA+200

H+200= H root 3 [USING i]

H (root 3-1) = 200

H= 200 /root 3-1
