Answer:
1. PLN = 140
2. PLM = 140
Step by Step Explanation:
1. KLP = MLQ
3x -5 = 2x + 10
3x -2x = 10 + 5
x = 5
KLP = 3x - 5
= 3(15) - 5
= 45 - 5
= 40 + 10 ( included in the question)
PLN = KLP + KLN
= 50 + 90
= 140°
2. PLO = QLN
4x - 30 = 3x - 10
4x -3x = -10 + 30
x = 20
PLO = 4x - 30
= 4(20) -30
= 80 -30
= 50
PLM = PLO + OLM
= 50 + 90
= 140°
