Answer:
∠ LKM = 125°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ LKM is an exterior angle of the triangle , then
3x - 70 = x + 60 ( subtract x from both sides )
2x - 70 = 60 ( add 70 to both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Then
∠ LKM = 3x - 70 = 3(65) - 70 = 195 - 70 = 125°
17/30
2/5+1/6=12/30+5/30=17/30
y=(-1/12)x+(-13/12)
