Question

Solve for the value of s.
(2S+2)°
(3S-2)

Answer 1

s = 18

Explanation:

the 3 angles (2s + 2)° , 90° , (3s - 2)° lie on a straight line and sum to 180°

sum the 3 angles, equate to 180 and solve for x

2s + 2 + 90 + 3s - 2 = 180 ( simplify left side )

5s + 90 = 180 ( subtract 90 from both sides )

5s = 90 ( divide both sides by 5 )

s = 18
