Given:
Height of the lighthouse = 280 feet
The angle of depression from the top of the lighthouse to a ship = 18°.
To find:
The distance between boat and shore.
Solution:
Draw a diagram by using the given information.
In a right angle triangle,

In triangle ABC,



Using a calculator, we get



Therefore, the boat is 862 feet away from shore.
The slope intercept formula: y=mx + b
2y - 8x = 20 ∫ Add 8x to both sides to make the equation suitable∫
2y = 8x + 20 ∫Divide both sides by 2∫
∵ y= 4x + 10 ∵
