Three friends, A, B, and C form the vertices (corners) of a triangle on flat ground.
Friend βAβ is standing directly at the bottom of a sheer cliff. Directly above A, at
the top of the cliff, a fourth friend, βDβ, is standing. The distance on the ground
between B and C is 400 m. The angle at βCβ between A and B is 35ΒΊ. The angle
at βBβ between A and C is 27ΒΊ. The angle of elevation from βCβ to βDβ at the top
of the cliff is 18Β° Find the angle formed at βDβ between βBβ and βCβ.
