We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall? The answer is to useSine, Cosine or Tangent!
We can find an unknown side in a right-angled triangle when we know: one length, and. one angle (apart from the right angle).
