Given:

The ratio is .

To find:

Inverse tangent of the given ratio.

Solution:

We know that,

Inverse tangent of the ratio =

                                                 =

Using scientific or graphing calculator, we get

Inverse tangent of the ratio =

Round to the nearest degree

Inverse tangent of the ratio

Therefore, the correct option is C.

1) 2/5
