Question

In an A-frame house, the two congruent sides each form a 76° angle with the ground. What is the angle formed at the peak by the two sides?

answer choices 76 14 104 28

Answer 1

So, this is basically saying that the frame forms a triangle.

All the triangles interior angles equal 180 degrees.

We know two angles are equal to 76 degrees.

76+76= 152

180-152= 28 dgrees

The angle at the peak is equal to 28 degrees.
