Answer:
15
Step-by-step explanation:
124° + 9x + 11 = 180 ➡ 9x = 135° ➡ x = 15
You divide the area by the base because A = bh, so you would use the algebraic expression (A/B)=H
Answer: 1,208 seats
Step-by-step explanation:
39-18= 21
18 x 478 = 8,604
21 x 292 = 6,132
8,604 + 6,132 = 14,736
14,736 - 13,528 = 1,208
