Question

Find the angle of elevation of the plane
When it reaches 300 feet above the ground.

Answer 1

X=36.87°

Explanation:

Tanx=opposite/adjacent

Tanx =300/400

Tanx=0.75

X=tan-¹(inverse)0.75

X=36.87°

Answer 2

36.78°

Explanation:

Use the tangent equation to find the solution.

Tangent = opposite/adjacent

tanx° =
`(300)/(400)`

x ≈ 36.78°
