Question

Solve for x. Round to the nearest tenth of a degree, if necessary.

Answer 1

`51.4^(\circ)`

Explanation:

Since this is a right triangle, the cosine formula says

`\cos(x) = (5.3)/(8.5)`

`\longrightarrow cos(x) = 0.6235`

`So\\\\x = \cos^(-1)(0.6235) = 51.4256^(\circ)`

Rounded to the nearest tenth this would be

`51.4^(\circ)`
