Answer :

First we need to find x

RS = PQ

x+ 3 = 2x

collect like term

2x - x = 3

x = 3

RS= x + 3 = 3+ 3 = 6

To find the angle, we need to find n

m< S and m < R are consecutive angles, hence its sum is equal 180 degree

That is;

m< S + m< R = 180°

10n° + 8n° = 180 °

18n° = 180°

Divide both-side of the equation by 18°

n = 10

m< S = 10 n° = 10(10) = 100°

m
