Explanation:

The trigonometric function cosine is defined as the following:


cos(A) = (adj)/(hyp)

where
A is any angle in a right triangle,
adj is the length of the side adjacent to angle
A, and
hyp is the length of the hypotenuse of the triangle.

For this problem, we can fill in these values as follows:


cos(A) = (10)/(17)

To solve for
A, we need to take the inverse cosine of each side:


cos^(-1)(cos(A)) = cos^(-1)((10)/(17))


A = cos^(-1)((10)/(17))

Resolving this with a calculator results in
53.986°, or rounded to the nearest tenth,
54.0°
