Answer:
40
Step-by-step explanation:
angles QPR and RPS are complimentary, so they equal 90, or angle QPS, so you can set up the equations like so:
7x - 9 + 4x + 22 = 90
Combine like terms:
11x + 13 = 90
Subtract 13 from each side:
11x = 77
Divide each side by 11:
x=7
Then use this value in the angle that you are finding:
7(7) - 9
49 - 9
40
40 is your answer
Hope this helps!
