Alakefront cottage that is 30 feet high casts a shadow on the water. how long is that shadow if a 16-foot-high truck parked nearby casts an 8-foot shadow?

15 ft

Step-by-step explanation:

We can use the properties of similar triangles.

16/8 = 30/x

   2 = 30/x     Multiply each side by x

 2x = 30           Divide each side by 2

   x = 15 ft

The shadow is 15 ft long.

Check:

16/8 = 30/15

      2 = 2
