Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I started this problem. I dont know really how to set it up. I attached my work. I know it is wrong but I do not know where. the correct answer is 42.2.

Here is the question:

A bridge over a river is supported by a hyperbolic arch which is 200 m wide at the base. The maximum height of the arch is 50 m. How high is the arch at a point 30 m from the center.

I drew a diagram (which I know is incorrect because my work assumes the center is (0,0)

Help.

If you have any ideas without looking at my work, anything will be appreciated. Thanks
