To solve for x, we can use the trigonometric function cosine, which is defined as the ratio of the adjacent side to the hypotenuse in a right triangle.
Given that the angle measures 31 degrees and the adjacent side measures 11, we can use the formula:
cos(31 degrees) = Adjacent / Hypotenuse
cos(31 degrees) = 11 / x
To find x, we can rearrange the equation and solve for x:
x = (11 / cos(31 degrees))
Using a calculator, we find:
x ≈ 15.74
Therefore, the correct answer is 15.7.
A right triangle has a corner that measures 31*, a hypotinuese of x, and an Adjacent of 11.
