Question

If lines f and g are parallel, m angle S = 6x - 15 and m angle U =8x -35 what is m angle Y?

10

45

96

135

Answer 1

45

Answer 2

s= 6x-15
U =8x -35

s = u
6x-15 = 8x -35
solve for x
20 = 2x
10 = x

now plug in the x value in to the expression
s=6(10) -15
s=60-15
s=45

u =8(10)-35
u = 80 -35
u =45

y would would have the same angle as s and u
