AC would be double of its angle, which happens to be 58.
58•2 = 116.
Therefore, your answer would be D: 116 degrees.
Step-by-step explanation:
Given
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
Suppose that a>b>1, then
and 
Therefore, since 2<3<7, 
Choose an arbitrary x>1. You have that a takes the greatest values at x, c takes the smallest value at x. Thus,
a>b>c and
Answer: correct option is B.
Use the pythagorean theorem. It would be set up as
a^2 + 3.7^2 = 4.0^2
