If WXYZ is a square with WZ = 27, find each measure.

a) ZY = d) mWRZ =

b) WY = e) mXYZ =

c) RX = f) mZWY =

To find the inverse of a number a, one can use the equation f(c) = a-1/c=0 where c is the inverse of a use the secant method of finding roots of equations to find the inverse of a = 2.5 ,er = 0.001%
