Find proportion of missing measure of a lighthouse casts 72 yard shadow at the same time as a 32 foot tall billboard casts a 19 foot what is the height of the lighthouse

1 answer

To find the height of the lighthouse, we can set up a proportion using the information provided:

Let x be the height of the lighthouse.

The proportion can be set up as follows:

x/72 = 32/19

Cross multiply to solve for x:

19x = 72 * 32
19x = 2304
x = 2304/19
x ≈ 121.26

Therefore, the height of the lighthouse is approximately 121.26 feet.
