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°
