Question

Where 0<=x<360, Solve the equation.
3sec(x)-8=0

Answer 1

\[3\sec x = 8\]\[\sec x = \dfrac{8}{3}\]\[\dfrac{1}{\cos x} = \dfrac{8}{3}\]\[\cos x = \dfrac{3}{8}\]

Answer 2

If x={68,292}, is there any way to do it without a calculator?

Answer 3

Well, you CAN construct a 17-gon with a straight edge and compass, but why?

Use the calculator.

Note: Are you SURE you want to go with no decimal places?
