Answer:
angle S 100 option C
Explanation:
P and S are consecutive angles
Interior angles of a parallelogram
1. Opposite angles are congruent
2. Consecutive angles are supplementary (They add to 180 )
(2x+20) + (3x+10) = 180
5x+30 = 180
5x = 150
x= 30
angle S 3x30 +10 =
90 +10 = 100
The other angle P 2x30 +20 = 60 +20 = 80
100 +80 = 180
