Answer:
24.1
Step-by-step explanation:
Use trigonometric ratios:
1) Set your calculator to degrees.
2) Since 15 degrees is given, use it in the tangent ratio, opposite over adjacent, which, in this case, is (x / 90)
3) Set up the equation:
[tex]tan(15) = \frac{x}{90}[/tex]
4) Multiply by 90 to isolate x:
[tex]90(tan(15)) = x[/tex]
5) Solve with a calculator to get
x ≈ 24.1
