Answer:

x =12

Step-by-step explanation:

The two angles add to 90 degrees

4x+4 + 5x-22 = 90

Combine like terms

9x - 18 = 90

Add 18 to each side

9x -18+18 = 90+18

9x = 108

Divide each side by 9

9x/9 = 108/9

x =12

Answer:

C.) 52°

Step-by-step explanation:

find x first

4x + 4 + 5x - 22 = 90

9x - 18 = 90

9x = 108

x = 12

plug it into the expression

4(12) + 4

= 48 + 4

= 52°
