Question

In the following figure, triangle ABC is a right triangle, and m A = 42°. Find the value of n°. Note: the figure is not drawn to scale.

Answer 1

As n is exterior angle ,

<A + 90 = n

n = 132°

Answer 2

Answer:

∠n = 132°

Step-by-step explanation:

As we know that exterior angle = Sum of opposite interior angles

→ ∠A + ∠B = ∠n

∵ ∠42° + ∠90° = ∠n

∴ ∠n = 132°
