Question

In the given figure, if l || m, and ∠a : ∠b = 2 : 3 , then find the value of y.

Answer 1

Answer:

108°

Step-by-step explanation:

let the ratio be x

A/q

=> 2x + 3x = 180

=> 5x = 180

=> x = 180/ 5

=> x = 36

therefore 2x= 2× 36 = 72

3x = 3 × 36 = 108

angle b = angle y ( corresponding angle)

So, therefore y = 108°
