How can we solve for angles in a right triangle given information about 2 sides.?

• By using the Pythagorean Theorem

• By using trigonometric ratios such as sine, cosine, and tangent.

• Solving for an angle using lengths of sides is not possible.

  We can only find an angle if we are given information about the other 2 angles. We then subtract their sum from 180 to find this angle.
