Answer: 80
=====================================================
Explanation:
Since QS is bisecting angle PQR, we have two identical triangles (aka congruent triangles)
The sides PS and RS are congruent corresponding pieces
PS = RS
6b-4 = 10b-60
6b-10b = -60+4
-4b = -56
b = -56/(-4)
b = 14
Therefore,
- PS = 6b-4 = 6(14)-4 = 84-4 = 80
- RS = 10b-60 = 10(14)-60 = 140-60 = 80
