Answer:
30°
Explanation:
You want the angle of elevation to a point 2900 feet up that is 5800 feet distant on a straight line.
Sine
The sine of the angle is the ratio of the height to the straight-line distance.
sin(θ) = h/d = 2900/5800 = 1/2
θ = arcsin(1/2) = 30°
The angle of elevation is 30° from the base to the top.
