I was wondering if you could help me out with some math problems Attached are the questions I would like to check my answers. If you could work a couple out so that I will make sure I am doing the work correct. I am having a hard time with this section of my class.

 

Thanks

An experimental model for a suspension bridge is built. In one section, cable runs from the top of one
tower down to the roadway, just touching it there, and up again to the top of a second tower. The towers
are both 6.25 inches tall and stand 50 inches apart. At some point along the road from the lowest point
of the cable, the cable is 1 inches above the roadway. Find the distance between that point and the base
of the nearest tower.
