Step-by-step explanation:

The given trigonometric equation is .

We take the inverse cosine of both sides to get:

to the nearest degree

None of the options satisfies the given equation.

But if the question is actually;

Then;

.

.

.

.

Or

.

In this case the answer will be B

3+x

step-by-step explanation:

30.5*10=350$
