From a boat 160 m out at sea, the angle of elevation to the coast is 18º. The angle of
elevation to the top of a lighthouse on the
coast is 22
a Draw a diagram representing the
situation.
b Find the height of the lighthouse.

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Me with geometry ! in this figure, bc is a perpendicular bisects of kj. dm is the angle bisects of bdj. what is the measure of bdm? •60° •90° •30° •45°
