Answer: s=7
Step-by-step explanation:
Use the supplementary angle theory as both angles are in a straight line of 180 degrees + a right angle (90 degrees)
(4s+8)+54+90=180
4s+152=180
4s=28
s=7
Answer:
s = 7
A straight line is 180 degrees.
=> 4s + 8 + 90 + 54 = 180
=> 4s + 152 = 180
=> 4s = 28
=> s = 7
