Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
For this case we have the following expression:

Rewriting the expression we have:
1) First we subtract the numbers within the parenthesis:

2) Then, we solve the exponents:

3) Then, multiplication:

4) Finally, the addition of numbers is made:

Answer:
