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

Base on my research and further computation, the possible answer of the angle X by using the tan-1, LKJ is equals to = 30 degree. I hope this helped :)

Answer 2

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.
