Question

Using the scientific calculator or graphing calculator find the inverse tangent of the ratio. Round to the nearest degree. 3/1

Answer 1

Given:

The ratio is
`(3)/(1)`.

To find:

Inverse tangent of the given ratio.

Solution:

We know that,

Inverse tangent of the ratio
`(3)/(1)` =
`\tan^(-1)(3)/(1)`

=
`\tan^(-1)3`

Using scientific or graphing calculator, we get

Inverse tangent of the ratio
`(3)/(1)` =
`71.565^\circ`

Round to the nearest degree

Inverse tangent of the ratio
`(3)/(1)\approx 72^\circ`

Therefore, the correct option is C.
