Calculating an Angle A water tower 30 m tall is located at
the top of a hill. From a distance of 120 m
down the hill it is observed that the angle formed between the top and base of
the tower is 8∘.
Find the angle of inclination of the hill.

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.
