I need Help with these questions PLEASE

1) C)↔PQ

2) C) 99

3) D) 48

Step-by-step explanation:

A line has no end points so c

add the two degrees together --> 18 + 81 = angle RST

plug the equation to each other cause their the same length

10x+8 = 14x-8

add 8 to both sides --> 10x+16 = 14x

subtract 10x from both sides --> 16 = 4x

now divide by 4 on both sides to get x alone

X = 4 -- plug it back into eqation 14x-8 to get the angle

14 x 4 = 56 - 8 = 48

true

explanation:

x=6 and x=3
