Question

From a boat on the lake, the angle of elevation to the top of a cliff is 14°28'. If the base of the cliff is 743 feet from the boat, how high is the cliff (to the nearest foot)?

Answer 1

@jim_thompson5910 I can't get this one. I keep getting a negative number. What am I doing wrong? :c

Answer 2

Tan angle = opposite angle/ adjacent

Answer 3

Tan 14°28= x/ 743

Answer 4

14°28 |x = 191.69 = 192

Did I get the right answer for this one?
A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed the angle of depression to the boat is 18°33'. When the boat stops, the angle of depression is 51°33'. The lighthouse is 200 feet tall. How far did the boat travel from when it was first noticed until it stopped?
