Answer:
55
Step-by-step explanation:
m< PTS = m< RTQ since they are vertical angles
11(y-10) = 4y-5
Distribute
11y - 110 = 4y-5
Subtract 4y from each side
11y-110-4y = 4y-5-4y
7y-110 = -5
Add 110 to each side
7y-110+110 = -5+110
7t = 105
Divide by 7
7y/7 = 105/7
y =15
We want to find m<PTS
m< PTS = 11( y-10) = 11(15-10) = 11(5) = 55
