Depth angle

From a cliff of 150 meters high, we can see the ship at a depth angle of 9° at sea. How far is the ship from the cliff?

Correct result:

x =  947.0627 m

Solution:

a=150 m A=909=81  tanA=x/a x=a tanA=a tan81 =150 tan81 =150 6.313752=947.063=947.0627 m



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
