Scary problem D:

Jay dives to a point T under the sea. A surface buoy is anchored at point P. Points S, R, and Q are at different distances from T as shown in the figure below. Segment ST is parallel to segment RQ.

Which equation can be used to find the correct value of the distance w, in feet, between the buoy and Jay?

hold on I'll write out the options

$$\frac{w}{w + 20} = \frac{35}{40}$$
Can you set up an equation from this?
