Answer:
x= 8
Step-by-step explanation:
Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.
3x + 12 + 7x + 88 = 180
Add like terms
10x + 100 = 180
-100. -100
10x = 80
/10. /10
x = 8
I believe it is 8
The angles combined should be 180
So, 180= 10x +100
Subtract 100 from both sides to cancel it out
80= 10x
Divide by 10 on both sides
8 = X
The angles combined should be 180
So, 180= 10x +100
Subtract 100 from both sides to cancel it out
80= 10x
Divide by 10 on both sides
8 = X
