#x~~1.504# radians

To solve for the angle #x#, let's take the inverse tan (arctan) of both sides. We get

#cancel(arctan)(cancel(tan)x)=arctan(15)#

#=>x=arctan(15)#

Evaluating with a calculator, we get

#x~~1.504# radians

Hope this helps!

#x = 86^@19 + k180^@#

tan x = 15
Calculator and unit circle give as general answer for x -->
#x = 86^@19 + k180^@#
