Question

Solve for x. Round to
the nearest tenth, if necessary.

Answer 1

24.1

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:

`tan(15) = (x)/(90)`

4) Multiply by 90 to isolate x:

`90(tan(15)) = x`

5) Solve with a calculator to get

x ≈ 24.1
