Question

what is the value of z? z 30°

Explanation:

Step1: Identify angle - relationship

Assume the angle formed is a right - angle (since no other information is given and it looks like a right - angle situation). A right - angle measures 90°.

Step2: Use angle subtraction

If the whole angle is 90° and one part is 30°, then to find z, we subtract the known part from the whole. So, $z = 90^{\circ}-30^{\circ}$.

Answer:

$60$
