# An exterior angle A. 45°

B. 65°

C. 25°

D. 135°

Answer :

Exterior angle formed when the side of a triangle is produced is equal to the sum of the interior opposite angles.

Exterior angle = 110°

One of the interior opposite angles = 45°

Let the other interior opposite angle = x

110° = 45° + x

x = 110° – 45°

x = 65°

Therefore, the other interior opposite angle is 65°.
