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:
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.
