Question

PLEASEE HELPPP MEE!!
what is the value of s?

Answer 1

s = 17

Explanation:

To solve, set the expressions equal to each other.

77 = (4s+9)

You want to get s by itself, so subtract the 9 from both sides.

77 = (4s+9)°

-9 -9

68 = (4s)

Divide by 4

68/4 = 4/4s

68/4 = 17

Alternate Interior Angles are always equal to each other.
