Answer:
∠WVU = 67°
Step-by-step explanation:
∠WVU = 1/2(arc WV)
8x + 11 = 1/2(15 + 17x)
8x + 11 = 7.5 + 8.5x
subtract 7.5 and 8x from each side of the equation:
0.5x = 3.5
multiply both sides by 2:
x = 7
∠WVU = 8(7) + 11 = 67°
proof:
arc WV = 15 + 17(7) = 134° which is 2 x 67°
Answer:
85
Step-by-step explanation:
Order of operations rules (PEMDAS) govern here. Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.
Add 2+5 first: 5 + 2*{(7)*5 + 5}
Perform the work shown inside the brackets { and }: 5 + 2*{40}
Perform the indicated mult.: 5 + 80
Finally, add: 85
