I have a problem, where I want to figure out how to split a triangle in two making two right triangles. The line has to be $90^\circ$ degrees from line $c$ (red font in picture), and has to meet with point $C$ (black font)
We know that The triangle is $73^\circ$ , $75^\circ$, and $32^\circ$, We also know that line $c$ is $8cm$. Is it possible to split it through mathematics?

The triangles are well defined. For each you know all the angles (75,90,15) and (72,90,18). You can use the law of sines to get the side lengths when you know one side.
