Answer:
z=24\°

Explanation:

We need to find the measure of "x":

Based on the figure, we know that:


48\°+x+x=180\°

Then, we need to solve for "x". Therefore, its measure in degrees is:


48\°+2x=180\°\\\\2x=180\°-48\°\\\\2x=132\°\\\\x=(132\°)/(2)\\\\x=66\°

By definition, the sum of the interior angles of a triangle is 180 degrees. Since we know the measure of "x" and we know that one of the interior angles is a the right angle (an angle that measures 90 degrees), we can conclude that:


z+90\°+x=180\°

Substituting the value of "x" into the equation and solving for "z", we get:


z+90\°+66\°=180\°\\\\z=24\°
