Aramp has a height of 3 feet and a base length of 12 feet. which of the following best represents the angle of elevation? a. 14° b. 16° c. 18° d. 20°

Modelling the ramp as right-angle triangle, we have the following diagram (attached)

We'll use one of the trigonometry ratios to find the elevation angle

We have the side that is adjacent to x° = 12 feet and the side that is opposite to x° = 3 feet, we will use the tan ratio

tan x° = opposite side / adjacent side
tan x° = 3/12
tan x° = 0.25
x° = tan⁻¹ (0.25)
x° = 14.03624347 ≈ 14°
