What kind of equation do I need to set up to solve this?

If the distance from the top of a building to the tip of its shadow is 150 feet and the sun makes a 75 degree angle with the wall as shown in the image below, what is the length of the shadow?

you have an angle--75-- so if you were to put that into a trig calculator and specify the function you would get a number , right?
