You may use the law of sines, that states that in every triangle the ratio between a side and the sine of the opposite angle is constant.
So, in your case, we have
We know that is 90 degrees, so its sine is 1. Also, we know that RS=26. So, the equation becomes
multiply the tops and bottoms, so:
1 * -5 * 3 = -15 for top
and
5 * 7 * 4 = 140 for bottom
then reduce by dividing by 5, and you get:
-3/28
