    3.Quilt squares are cut on the diagonal to form triangular quilt pieces. The hypotenuse of the resulting triangles is 34 inches long. What is the side length of each piece? a. 34 sqrt2 inches b. 17 sqrt3 inches c. 17 sqrt2 inches d. 13 inches

    So since it is cut out of a square...we have the same 45 45 90 triangle thing... now we know the hypotenuse is 34 So that means the other 2 legs...would be a number times √2 that would = 34 \[\large x√2 = 34\] \[\large x = \frac{34}{√2}\] \[\large x = 17√2\]

    Good idea :) But how would you put what in the calculator? There is a function key for square roots and everything on there (or at least should be)

    Well for that we have \[\large sin(x) = \frac{7}{12}\]so\[\large x = \sin^{-1}(\frac{7}{12})\]

    and if there is no (2nd) button...just look for a \(\sin^{-1}\) button or an \(\text{arcsin}\) button

    Ahh you ARE in radian mode.... Look for a button that says \(\large \text{rad}\) or \(\large \text{deg}\) you want to be in deg "degree" mode

    Now you see there is a "units" thing with radians and degrees next to it....click degrees And do the calculation over again...go over and hit the \(\large \sin^{-1}\) button and put in 7/12 :)
