Therefore, the two other interior angles measure 64° each, since this is an isosceles triangle with two equal sides.
Since the exterior angle forms a supplementary angle with the interior angle of 64°, you can subtract 64 from 180 to get the other part of the supplementary angle:
180-64=116
Therefore, the measure of the exterior angle is 116°.
Im not sure but since the angle you have is 52 and this is an isosceles triangle so you will do 180-52 over 2 to get the other 2 angles which will be 64 each and you want the exterior angle which is 180 aswell so you will do 180-64 which will be 116
