Question 1030982: I need to solve for X. I can solve the equation when given the information but I can not find X in the equation. For example:
2*arctan(36/(43*2))
2*arctan(36/86)
2*arctan(0.4186046512)
2*22.71441235
=45.42882471
Note: Working in degrees and not radians
Here is the equation with the variable x.
90.36=2*arctan(36/(2*x))

You can put this solution on YOUR website!
90.36=2*arctan(36/(2*x))
45.18 = arctan(36/(2*x))
45.18 = arctan(18/x)
tan(45.18) = 18/x
1.0063 = 18/x
x = 18/1.0063
x =~ 17.8873
