Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
Answer:(x-3) (x+3)
Step-by-step explanation:
Add 't' to both sides. t+r=s
