Question

To the nearest degree, determine the measure of angle X for each value of
tan X
a. tan X = 0.49

Just not sure how to solve these questions

Answer 1

Tan^-1(0.49) is not one of those which have exact answers. You will have to resort to a calculator or a table of tangents.
On a calculator, enter 0.49 and press the button tan^-1, which is usually preceded by a yellow key, and is written above the tan key. I get about 26°.

Answer 2

On ur calculator there’s a “tan” button, u need to find the “tan -1” button by either pressing “2nd” or smt like that. Then u should see “tan -1 (“ write the number and close the brackets, u should get ur degree, hope it helps :)
