Question

If l is Parallel to m, find the value of y

Answer 1

Step-by-step explanation:

1st

8x-59 + 2x-11 = 180

10x -70 = 180

10x = 180 + 70

10x = 250

x = 25

2nd

8x - 59 = 15y + 6

8(25) -59 = 15y + 6

200 -59 = 15y + 6

141 = 15y + 6

15y + 6 = 141

15y = 141 - 6

15y = 135

y = 135/15

y = 9

Answer 2

Answer:

y=9

Step-by-step explanation:

A line is equal to 180°.

8x-59+2x-11=180

10x-70=180

$\frac{10x}{10} =\frac{250}{10}$

x=25

8(25)-59=141°

2(25)-11=39°

(8x-59)° and (2x-11)° are complementary, so 141 + 39=180

(15y+6)°= (8x-59)°

15y+6= 141

15y=135

y=9
