Answer:
Step-by-step explanation:
6x + 12 + 4x + 8 = 180 {Linear pair}
6x + 4x + 12 + 8 = 180 {Combine like terms}
10x + 20 = 180 {Subtract 20 from both sides}
10x = 180 - 20
10x = 160 {Divide both sides by 10}
x = 160/10
x = 16
m∠KLJ = 6*16 + 12
= 96 +12
= 108
m∠JLM = 4*16 + 8
= 64 + 8
= 72
∠ KLJ = 108° , ∠ JLM = 72°
Since the angles are a linear pair they sum to 180° , then
6x + 12 + 4x + 8 = 180
10x + 20 = 180 ( subtract 20 from both sides )
10x = 160 ( divide both sides by 10 )
Then
∠ KLJ = 6x + 12 = 6(16) + 12 = 96 + 12 = 108°
∠ JLM = 4x + 8 = 4(16) + 8 = 64 + 8 = 72°
