Question

In Paralellogram ABCD,Angle A=2x15° and angle B=3x-25°,find x​

Answer 1

Step-by-step explanation:

Given the parallelogram ABCD.

In case of a parallelogram the sum of co-interior angles will be 180°

i.e, ∠A+∠B=180°

⇒2x+15+3x−25

o

=180°

∴5x=190°

i.e, x=38°

Hence, the answer is 38°.
