Answer:
249 feet
Explanation:
Hello!
Let the missing side be x.
We can use a trigonometric ratio to solve this question. The one we are going to use is Tangent.
There are 3 trigonometric ratios: Sin (Opposite/Hypotenuse), Cos (adjacent/hypotenuse), and Tan(Opposite/Adjacent).
We need to use the ratio that involves the 2 sides, 144 and x. That would be Tan, as x is opposite to 60°, and 144 is adjacent to 60°.
Solve for x:
- tan(60) = x/144
- tan(60) * 144 = x => Plug tan(60) into a calculator, and multiply the result by 144.
- 249.415... = x
- x ≈249
The missing side is 249 feet.
