Look pls this is about angles and I don’t understNd it at all

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
