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.

Angle LKJ (x) = 45 degree and round to 50 degree.

Step-by-step explanation:

Given : The equation tan−1 = x can be used to find the measure of angle LKJ.

To find : What is the measure of angle LKJ and Round to the nearest whole degree.

Solution : We have given tan^{-1}(1)  = x .

Taking tangent both side equation become

         1 = tan (x).

By the trigonometry rule tan(45) = 1

Plugging the value of 1 = tan (45).

tan(45) = tan (x)

Then  x = 45 degree.

Therefore, angle LKJ (x) = 45 degree and round to 50 degree.
