------------------------------------------------ In triangle FGH, if [tex]\angle H = 90^\circ[/tex], [tex]\angle F = 15^\circ[/tex], and GH = 57 feet, what is the length of FG to the nearest tenth of a foot?

Answer :

Final answer:

To find the length of FG in triangle FGH, we can use the trigonometric ratio of tangent. Applying this, we find that the length of FG is approximately 15.3 feet.

Explanation:

To find the length of FG in triangle FGH, we can use the trigonometric ratio of tangent. Since we know that ∠H is a right angle, we can use the tangent of ∠F to find the length of FG. The tangent of ∠F is equal to the opposite side (FG) divided by the adjacent side (GH). So we can set up the equation tan(∠F) = FG/GH and solve for FG. Plugging in the values we have, tan(15°) = FG/57. Using a calculator, we can find that tan(15°) ≈ 0.2679. Multiplying both sides of the equation by 57, we get FG ≈ 15.3 feet.
