If you look from the $\displaystyle \displaystyle \begin{align*} 27^{\circ} \end{align*}$ angle, then you set up your ratio as $\displaystyle \displaystyle \begin{align*} \sin{\left( 27^{\circ} \right)} = \frac{y}{6.2} \end{align*}$ and solve for y.

If you look from the $\displaystyle \displaystyle \begin{align*} 63^{\circ} \end{align*}$ angle, then you set up your ratio as $\displaystyle \displaystyle \begin{align*} \cos{ \left( 63^{\circ} \right)} = \frac{y}{6.2} \end{align*}$ and solve for y. - Jan 13th 2013, 10:01 PMVince604Re: How Do I Find X and Y If Hypotenuse is Given (Trigonometry)

You can see that y has been DIVIDED by 6.2, so to undo this, you need to MULTIPLY both sides by 6.2
