We set up a proportion: 84/?= 56/100
Cross multiply: 56*?= 84*100
⇒ ?= 84*100/56= 150
56% of 150 is 84.
Answer:
452.39 mi^2
Step-by-step explanation:
A = πr^2
A = π (12mi)^2
A = 452.39 mi^2

The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
Answer:
See below
Step-by-step explanation:
Remark
Base angles of Isosceles triangles are equal.
Equation
That means that 8x + 14 = 14x - 15
Solution
8x + 14 = 14x - 15 Add 15 to both sides
8x + 14+15 = 14x Combine
8x + 29 = 14x Subtract 8x from both sides
8x - 8x + 29 = 14x - 8x Combine
29 = 6x Divide by 6
x = 29/6
x = 4 5/6
Answer
x = 4 5/6 or 4.833
8x + 14 = 8 * (4 5/6) + 14
8x + 14 = 38 2/3 + 14
8x + 14 = 52 2/3 or 52.6666
14x - 15 = 14 *(4 5/6) - 15
14x - 15 = 67 2/3 -15
14x - 15 = 52 2/3 or 52.666
