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°.
120%
Take 750 divided by 625. That equals 1.2, then multiply 1.2 times 100 to reach the final answer of 120%
