Question

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

9.5

Answer 1

Hit the second button on your calculator and then the tan button and you will see this on your screen:
`tan ^(-1)(`. It is after that parenthesis that you enter your 9.5. The angle that gives us a tangent of 9.5 is 83.99° or 84°

Answer 2

The value of inverse tangent of 9.5 is 83.9°.

Explanation:

We are required,

To find the inverse tangent of 9.5

That is, we have to find
`\arctan 9.5`

Using the scientific calculator, we have that,

`\arctan 9.5=1.465` (in radians)

Since, 1 radian = 57.3°

Then, 1.465 radian = 83.9°

Hence, the value of inverse tangent of 9.5 is 83.9°.
