Answer:
angle BAC = 116
Step-by-step explanation:
since the triangle is isosceles and AB and AC are congruent, that means angle ABC and angle ACB are the same by the isosceles triangle theorem. so you know angle ABC and angle ACB are 32 and all angles in a triangle equal to 180. so you find angle BAC subtracting both of the 32 angles from 180 and you should get 116
