sin32=opposite/hypotenuse, which is 12.87/23.96. (12.87/23.96)/12.87=
12.87/(23.96*12.87)=1/23.96.
For the right side to be equal, it must have 22.35 on the top (to cancel out) and 23.96 on the bottom. Since 23.96 is the hypotenuse, we have that, and since 22.35 needs to be on the top, sin67 fulfills that
