38

Explanation:

Answer 2

The three inside angles of a triangle need to equal 180 degrees.

In a right triangle one of the angles is 90 degrees.

This means the other two angles need to equal 180-90 90 degrees.

You are given one of the angles of 52 degrees, so subtract that from 90 to find the third angle.

90 - 52 = 38 degrees.

The answer is A.
