You have three options, all of them work. sin(angle) = opposite/hypotenuse cos(angle) = adjacent/hypotenuse tan(angle) = opposite/adjacent You are already given the length of the lines, so all you can is to take the inverse of whatever you choose to get the angle. [latex] sin^{-1} [/latex] (5/13) = 22.62 [latex] cos^{-1} [/latex] (12/13) = 22.62 [latex] tan^{-1} [/latex] (5/12) = 22.62
