Answer:
47
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
9x+2 = 23+ 5x-1
Combine like terms
9x+2 = 5x+22
Subtract 5x from each side
9x+2-5x = 5x+22-5x
4x+2 =22
Subtract 2
4x +2-2 =22-2
4x= 20
Divide by 4
4x/4 =20/4
x=5
We want to find
<PRS = 9x+2 = 9(5)+2 = 45+2 = 47
