Answer»

Answer:

AB = AB

AD = BC

AC = BD

∠DAB = ∠CBA

∠DBA = ∠CAB

∠ADB = ∠BCA

Step-by-step EXPLANATION:

We have,

ΔDAB and ΔCAB

Now,

In ΔDAB and ΔCAB,

∠DAB = 45° + 30° = 75°

∠CBA = 45° + 30° = 75°

So,

∠DAB = ∠CBA [Angle]

AB = AB [Common Side]

∠DBA = ∠CAB = 30° [Angle]

Hence,

ΔDAB ≅ ΔCBA (By A.S.A. Congruency)

So,

AB = AB

AD = BC

AC = BD

∠DAB = ∠CBA

∠DBA = ∠CAB

∠ADB = ∠BCA

Find the angles of a triangle PQR if P-Q=45° and Q-R=30°​

Answer»

ANSWER:

Step-by-step explanation:

If P - Q = 45. Therefore, P = Q + 45. Also, Q - R = 30, therefore R = Q - 30. In TRIANGLE PQR P+Q+R = 180 i.e. Q+45+Q+Q-30=180 i.e. 3Q + 15 = 180 i.e. 3Q = 165 i.e. Q = 55 Therefore P = 55 + 45 = 100 Q = 55 and R = 55 - 30 = 25

Rahul travels first 50 km at 10 kmph, next 40 km at 20 kmph and then next 60 km a 15 kmph.Find his average speed for the whole journey.​

Answer»

SPEED = DISTANCE /TIME

1) s1/t1= 50/10= 5 hours

2) s2/t2=40/20=2 hours

3) s3/t3=60/15=4 hours

Average Speed= TotalDistance/Totaltimetaken

s1+s2+s3/t1+t2+t3

50+40+60/5+2+4 = km/hr

150/11= 13.6363636364

approximately 13km/hr

ANS= 13.6363636364

8. The area of a rectangle is 24 sq.cm. If the length of the rectangle is 8 cm find its breadthand cost of fencing it at the rate of Rs. 2 per metre.​

Answer»

Given:

  • Area of RECTANGLE = 24 m²
  • Length of rectangle = 8 m

To find:

  • Breadth of the rectangle
  • Cost of fencing the rectangular plot of land at ₹2 PER m.

Solution:

As we have to find the cost of fencing the rectangular plot of land, i.e. the PERIMETER of the rectangle, first its necessary to know the breadth of the rectangle.

We know that,

\boxed {\mathfrak {\orange {Area\ of\ rectangle = l \times b}}}

24 = 8b

\sf \dfrac {24}{8} = b

\bigstar {\bf {\pink {3\ m = breadth}}}

Now,

\boxed {\mathfrak {\blue {Perimeter\ of\ rectangle = 2(l+b)}}}

Perimeter = 2(8+3)

Perimeter = 2×11

\bigstar {\bf {\red {Perimeter = <klux>22</klux>\ m}}}

Cost of fencing 1 m plot of land = ₹2

Cost of fencing 22 m plot of land = 2×22

= ₹44

Cost of fencing:

Cost of fencing the rectangular plot of land is 44.

72a 384 is a number in which one of the digits is "a" it the number is exactly divisible by 9.what is the value of "a"​

Answer»

Answer:

The number was 723384.

Step-by-step explanation:

We have,

72a384 which is a number where 'a' is ONE of its digits, and it is divisible by 9.

Now,

We know that,

If a number is divisible by 9, its complete sum MUST be equal to 9

Here, adding the digits, we get,

7 + 2 + a + 3 + 8 + 4

= 9 + a + 11 + 4

= a + 24

Since a is a single digit, TAKING complete sum,

= a + 2 + 4

= a + 6

Now,

a + 6 should be equal to 9

So,

a + 6 = 9

a = 9 - 6

a = 3

So,

The number was 723384.

the ratio of tens digit to one's digit of a number is 2:3 .if 27 is added to the number the digits interchange their places.find the number​

Answer»

Answer:

The number is 69

Step-by-step EXPLANATION:

LET the number be 10m + n

where m is the digit in tens PLACE and n is the digit in ones place.

So, reversing it we will get,

10n + m

Now, we are given,

m : n = 2 : 3

So,

Let m = 2x and n = 3x

Then,

The number becomes,

10(2x) + (3x)

= 20x + 3x

= 23X

Then,

The reversed number becomes,

10n + m

= 10(3x) + (2x)

= 30X + 2x

= 32x

Now, according to the Question,

Number + 27 = Number reversed

23x + 27 = 32x

Solving for x,

32x - 23x = 27

9x = 27

x = 27/9

x = 3

Hence,

m = 2x = 2(3) = 6

n = 3x = 3(3) = 9

So,

The original number becomes,

10m + n = 10(6) + (9)

= 60 + 9

= 69

Hence,

The number is 69.

Hope it helped and believing you understood it....All the best

Construct a line through Q which parallel to X and Y​

Answer»

Step-by-step explanation:

The POINT P=(p,Q)=(3,4) and a line is drawn parallel to Y-axis.

Therefore, TH equation of the line is x=p=3

Again ANOTHER line is drawn parallel to X-axis through a point Q=(r,s)=(1,−7)

Therefore, the equation of the line is y=s=−7

Therefore, the lines are x=3 and y=−7

Therefore, the point of intersection is

(x,y)=(3,−7)

Answer»

Given:-

Speed of Bus = 42km/h

Time taken to Cover Distance = 5h

To Find:-

How MUCH time would it save if it's speed is increased by 8 km/h.

Formulae used:

Distance = Speed × Time

How To solve?

First we will find the total Distance covered by the bus.

After that we will find the time taken to Cover same distance if speed increases as per given

Now,

→ Distance = Speed × Time

→ Distance = 42 × 5

→ Distance Covered = 210km

Hence, The Total Distance covered by bus is 210km

ATQ,

If the SPEED is increased by 8km/h

Therefore,

→ New Speed = 42 + 8 → 50km/h.

Now,

→ Distance = New Speed × Time

→ 210 = 50 × Time

→ Time = 210/50

→ Time = 4.2h

So, The new time taken by car to cover same distance after the INCREASE in speed is 4.2h

So,

→ Time SAVED = Original Time - New Time

→ Time saved = 5 - 4.2

→ Time Saved = 0.8h

So, The Time saved by bus is 0.8h.
