Answer:
z = 38 degrees
Explanation:
As we can see in the picture that the triangle is a right angle triangle and two of the angles are known.
We also know that the sum of internal angles of a triangle is 180 degrees.
We know that one angle is 90 degrees and second is 52 degrees.
So,
Sum of three angles = 180 degrees
90 + 52 + z = 180
z = 180 - 90 - 52
z = 38 degrees ..
