Answer:
.75
Step-by-step explanation:
1/4 OF 1 IS 25. 1.00-.25 IS .75.

Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around
170
∘
, but we can rule that out as a value for a ramp wedge angle.
I might be wrong but 9
9*2=18
18+7= 25
25 square root = 5
