<span>(A) Find the approximate length of the plank. Round to the nearest tenth of a foot.
Given that the distance of the ground is 3ft.
In order to get the length of the plank,
we can use the this one.
cos 49 = ground / plank
cos 49 = 3 / plank
plank = cos 49 / 3
plank = 0.10 ft
</span><span>(b) Find the height above the ground where the plank touches the wall. Round to the nearest tenth of a foot.
</span><span>
The remaining angle is equal to
angle = 180 - (90+49)
angle = 41
Finding the height.
tan 41 = height / ground
tan 41 = height / 3
height = tan 41 / 3
height = 0.05 ft.
(A) 0.10 feet
(B) 0.05 feet</span>

We want to find out how much it costs for each pound of feed

For goat feed 75 divided by 60
$1.25 for 1 pound of goat feed
For dog feed 50 divided by 37.50
$1.33 for 1 pound of dog feed
For pig feed 80 divided by 62.80
$1.27 for 1 pound of pig feed
When reviewing all the answers per pound for feed, chicken feed is the most expensive per pound.
