Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)
The answer is x = -2 you move the all x to one side and all numbers to the other side. then divide to find x
Answer:
2s(s + 5)= 8
