Answer 2

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`°
