Observe the figure below.
When two lines intersect each other, vertically opposite angles are always equal.
So,
So, the measure of 'y' is 15 degrees.
The measure of angle PTS = 11(y-10)
= 11(15-10)
= 55 degrees
So, the measure of angle PTS is 55 degrees.
STR and QTP are both equal 180 so PTS +PTR=180 andQTR+PTR=180 which means PTS=QTR(for a shorter explanation they are staying against each other in a line cross 11y-110=4y-5 7y=105 y=105:7 y=15 grafe which means PTS y*4-5=55 grade
