Find Solution to Equation - URGENT!

Question

8 = 4 tan(5x)

Answer 1

8 = 4tan(5x)

tan(5x) = 8/4

tan(5x) = 2

5x = tan^-1(2) = the angle whose tangent is 2= about 63.435 degrees or 180+63.435 = 243.435

and both solutions + 360n where n= any integer

found by using a calculator with a trig function

5x = 63.435 or 243.435

x = 63.435/5 or 243.435/5

x = about 12.687 degrees or 48.68699 degrees are the basic answers
