(I don't have the symbols on my computer to write this exactly like on the page, but it is 11 by square root of two, over 12). Answer by stanbon(57307)   (Show Source): You can put this solution on YOUR website!Find the cos (theta) if csc theta) = 11 square root of 2 divided by 12 ------------------ General Form: csc(theta) = r/y ------- Your Problem: csc(theta) = [11sqrt(2)]/12 , so r = 11sqrt(2) and y = 12 Find x: x = sqrt(r^2-y^2) = sqrt[121*2 + 144] = sqrt(386) ------------------ Since cos(theta) = x/r, cos(theta) = sqrt(386)/11sqrt(2) = sqrt(193)/11 ======================================== Cheers, Stan H.
