Let \(a\) and \(b\) be positive lengths, and consider the following triangles:

Then what are

\(\angle A, \angle D, \angle G\)

in radians, in that order?

Use Law of Cosines for all three problems and you should get the answer pretty quickly.

\(\angle A = \frac{5\pi}{6}\)

\(\angle D = \frac{\pi}{2}\)

\(\angle G = \frac{\pi}{4}\)
