Need help with geometry question

B. 66

Step-by-step explanation:

idk how to explain it without repeating what it says in the answer

The answer is:

B) 66 degrees

Step-by-step explanation:

Since the triangle is an isosceles triangle, angle C is the same as angle B.

57 + 57 = 114

Since you know two of the three angles, and you know that a triangle's angles must equal 180 degrees...

180 - 114 = 66

Angle A must equal 66 degrees for the triangle to equal 180 degrees.
