    I'm stuck on a question in my C4 textbook and would really appreaciate some help.
    Given that tan26.6=0.5, solve tanx=2 without using your calculator. Give x to 1 decimal place where 0<x>90
    I know that 4tan26.6=2 not sure what else to do, this is just after they introduced the reciprocal trig functions, compound angle formula and the double angle formula if that helps.

    Draw yourself a right angled triangle with an angle of 26.6 degrees in it. Make the opposite side 1 unit and the adjacent side 2 units, so it has a tangent of 0.5. What angle do you think might have a tangent of 2?
