Answer:
7066.66666667
Step-by-step explanation:
Sorry if i'm wrong
A graph shows x-3 to be a factor, selection B.
The factorization would be (7x +3)(x -3).
This is the concept of trigonometry, the height of the ramp will be given by:
sin theta=[opposite]/[hypotenuse]
theta=30
opposite=x
hypotenuse=40 ft
hence;
sin 30=x/40
thus;
x=40sin30
x=20 ft
the ramp is 20 ft high
