I'm pretty sure the answer would be 14 inches
Answer:
The angle of elevation is <span><span>26.5650</span><span>(3dp)</span></span>
Explanation:
Let h be the end height of the ramp above the ground , l be the length of the ramp and the angle of elevation is <span>θ∴<span>tanθ</span>=<span>hl</span>=<span>510</span>=0.5∴θ=<span><span>tan<span>−1</span></span><span>(0.5)</span></span>=<span>26.5650</span><span>(3dp)</span></span>[Ans]
There isn't enough information; however, let's say you were to find the missing side length of a rectangle. The perimeter is 52 and the two given side lengths are both 16. You would set up an equation to find the missing side lengths:
52 = 16 + 16 + ? + ?
52 = 32 + ? + ?
20 = ? + ?
Since this is a rectangle, the two other sides have to be equal. Therefore, you would divide the number by 2.
10 = ?
