Answer:

a = 57.5

b = 57.5

Answer:

Angle A=57.5º

Angle B=57.5º

Step-by-step explanation:

A straight line is 180º

180º-65º=115º

115º/2=57.5º

Angle A=57.5º

Angle B=57.5º

Just in case for the interior angles(c & d):

The triangle given is an issoceles triangle meaning the bottom two angles are the same.

All the angles in a triangle add up to 180º

180º-65º=115º

115º is the sum of the two bottom angles

115º/2=57.5º
