Answer:
10.5%
Step-by-step explanation:
The tangent of the angle is the ratio of rise to run.
tan(angle) = grade
tan(6°) ≈ 0.105 = 10.5%
The grade will be 10.5% for an angle of elevation of 6°.
Three equivalent ratios are: 8/6, 12/9, 16/12
The one with (1, 10) and (1, 15) because in a function the same x value cannot equal different y values
