Triangle ABC is a right triangle, with B being the right angle and line CB being the ground. An obtuse triangle is inside triangle ABC. Let's call this obtuse triangle ADC.

The diagram should look something like this:

Suppose angle ACB=24.4 degrees and angle ADB=58.3 degrees, and CB=169 units.

AB should 106.5 units, but how do you solve this? Please explain the steps using sine, cosine and tangent ratios involving a right triangle.
