9. Imagine you are an engineer and you are in charge of building a bridge and the bridge is going to
look like as shown below. You can see that the bridge is enclosed in a kind of metal cage that holds it
up. The cage is longer at the bottom than at the top and it has slanted sides. Let's say the top of the
bridge is 500 ft and the bottom of the bridge is 750 ft. You want to build an extra support beam
where the purple line is. Do you know how long you would need to make the support beam?
