Raj is viewing the coast from the top of a lighthouse at sea (D). The lighthouse is 420 m from a cliff (AC). Raj measures the angle of elevation to the top of the cliff (A) to be 28° and the angle of depression to the bottom of the cliff (C) to be 18°. The information is represented in the following diagram: 420 m 28° 18° How high is the cliff? Give your answer correct to the nearest metre.
