The boat is 428.9 feet from the lighthouse.
To solve this, draw a right triangle. You will see that you have an angle of 25 degrees with an opposite side of 200 and the adjacent side is x.
We can write and solve the following tangent equation:
tan(25) = 200 / x
x = 200 / tan(25)
x 428.9
Write the decimal number as a fraction
(over 1)
3.1818 = 3.1818 / 1
Multiplying by 1 to eliminate 4 decimal places
we multiply top and bottom by 4 10's
Numerator (N)
N = 3.1818 × 10 × 10 × 10 × 10 = 31818
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 = 10000
N / D = 31818 / 10000
Simplifying your fraction
= 31818/10000
= 15909/5000
= 3 909/5000. Hope this helped!!!
