Answer:
55
Explanation:
We are given with two lines that intersects each other .
the vertical opposite angles are same.
So we equate the angles and solve for y


Subtract 4y from both sides

Now we add 110 on both sides

Now we divide by 7 on both sides
y=15
now we find m∠PTS
m∠PTS=

Plug in 15 for y
m∠PTS=
