The tow truck was towing a car, the car is 10 ft long and cast a shadow 23 ft long if the tow truck is 17 ft long how long is the shadow of the tow truck

the lengths and shadows are in the same ratio. So,
10/17 = 23/x
x = 39.1 ft
or, the ratio of length:shadow is the same for both vehicles:
10/23 = 17/x
x = 39.1 ft
