• Let 2nd side have length x 1st side = 2x -65 3rd side = x -10 So 2x-65 + x + x-10 = 165 4x -75 = 165 4x = 165 +75 = 240 …

• Let x = number quarters So 2x = number of dimes //// There are twice as many dimes as quarters & (2x+7) = number of nickels ///// There are seven more nickels than dimes 5(2x+7) + 10(2x) + 25x = 310 10x +35 +20x +25x = 310 55x = 310 -35…

• 12cos^2 x=3 cos^2 x = 3/12 = 1/4 cos x = +/- 1/2 either x = cos^-1 ( 1/2 ) = pi/3 or 5pi/3 or x= cos^-1 ( -1/2) = 2pi/3 or 4pi/3
