Answer:
s = 15
Step-by-step explanation:
We know that a straight line measures 180°
so… in order to find the value of s add the two angles with a sum of 180 and then solve for s
(9s + 8)° + 37° = 180°
Combine like terms
9s + 45 = 180
Subtract 45 from both sides
9s = 135
Solve for s
s = 135/9
s = 15
