Question

two adjacent of a parallelogram are as 2:3 fin the measure of each of the angle B , angle C ​

Answer 1

Answer:

Let, angle B and angle C are adjacent angle.

Ratio of angle B and angle C = 2 : 3

Let, angle B = 2a

angle C = 3a

Sum of adjacent angle = 180 degree

So,

2a + 3a = 180

=> 5a = 180

=> a = 180

____

5

=> a = 36

angle B = 36 × 2 = 72 degree

angle C = 36 × 3 = 108 degree

Ans. angle B = 72 degree, angle C = 108 degree

Hope it helps.
