Answer 1

Answer:

108°

Step-by-step explanation:

In the given figure, ∠a and ∠b is linear pair,

So, the sum of the ∠a and ∠b  = 180° (Linear pair)

Let's take the angles as 2x and 3x

2x+3x = 180° (Stated above)

5x= 180°

x= 180/5

x= 36°

2x = 2*x = 2*36 = 72°

3x = 3*x = 3*36 = 108°

∠b=∠f = 108° (Corresponding angles)

∠f =∠h= 108° (Vertically opposite angles are equal)

∴ The measure of ∠h is 108°
