Answer:
its C
Step-by-step explanation:
Just divide by 12 because they're are 12 inches in a foot. 240 ÷ 12 = 20
ANSWER: square root of 10
Rule: Pythagorean Theorem (a^2 + b^2 = c^2; side^2 + second side^2 = hypotenuse^2)
(substitute the missing side w/ a variable)
x^2 + 7^2 = (sqrt. 59)^2
x^2 + 49 = 59
x^2 = 10
x = sqrt. 10
6 = 2(x + 8) - 5x
6 = 2x + 16 - 5x
6 = 16 - 3x
3x = 16 - 6 = 10
x = 10/3
