The question is 

Jamie is surveying a cliff to determine the elevation from the base of a canyon to the top of the cliff. She lays out a line $AB$ that is $225 m$ in length. She also sites a point $C$ at the base of the cliff. Point $D$ is a point directly above point $C$, at the top of the cliff. She measures to be $43°$, to be $58°$, and the angle of elevation from point $A$ to point $D$ to be $29°$.

Here's my model

What I did to measure to find C:

1. $C: 180-43-58 = 79°$

This is where I'm stuck. I don't really know where to go.

Please help. Thanks a lot.
