Answer:
-20
Step-by-step explanation:
let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20

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

, but we can rule that out as a value for a ramp wedge angle.
Cos(x) = sin(90 - x)
cos(53) = sin(90 - 53)
cos(53) = sin(37)
The formula that should be entered in A3 is = A1 * B1
<h3>How to determine the formula?</h3>
The question implies that:
A3 = A1 times B1
In mathematics, the term "times" means *
So, we have:
A3 = A1 * B1
Remove the variable A3
= A1 * B1
Hence, the formula that should be entered in A3 is = A1 * B1
