Answer:
10.5 Degree.
Step-by-step explanation:
The inclined length of the ramp is 16' i.e. 16 feet i.e. (16 × 12) = 192 inches.
And the rise of the ramp is 35" i.e. 35 inches.
We have to calculate the degree of slope from the above information.
If we consider the ramp as the hypotenuse of a right triangle, then the perpendicular height is 35 inches.
Then angle of slope is given by

⇒
degree. (Answer)
U set up an equation: 80 x 8/5
Then u can cross multiply bc 5 goes into 80
It goes into 80 exactly 16 times
So new equation: 16 x 8
Multiply that out and u get 128
9 4/9
1. convert 3 1/3 to have a denominator of 9
2. 3 1/3 x 3/3 = 3 3/9
3. 6 1/9 + 3 3/9 = 9 4/9
