Question

The equation tan−1 = x can be used to find the measure of angle LKJ. What is the measure of angle LKJ? Round to the nearest whole degree.

Answer 1

Answer:

            x = 45       &         x = 225

Step-by-step explanation:

The equation given in the question is

tan^-1 (1) = x

We can re-write this equation as

 tan x = 1

The Reference Angle is 45 degrees

tan is +ve in Quadrant (i) and Quadrant (iii)

For Quadrant (i) : x = 45

For Quadrant (iii) : x = 180 + 45 =225

So the answer of the equation tan^-1 (1) = x is

x = 45  & x = 225
