Answer:
AC = 10sin 40°
Step-by-step explanation:
From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.
Thus, since we want to find AC;
We know that in trigonometric ratios; opposite/hypotenuse = sin θ
In the diagram, θ = 40° and AB = 10
Thus,
AC/10 = sin 40°
Multiply both sides by 10 to get;
AC = 10sin 40°
Answer:
4 bag's
Step-by-step explanation:
Given the bean bag made by beth is in the shape of cube with each side of the cube equal to 2 feet.
Now Also given that each bean bag holds 2 cubic feet of beans.
Let the number of bags of beans recquired are x
The total number of beans available are 2x cubic feet
Now the volume of the bean bag made by beth is
Volume =
Volume = 8 cubic feet
Now 8 = 2x
x = 4
Therefore the number of bag's of beans recquired are 4
