Answer:
Step-by-step explanation:
Angle E is one-half the measure of the difference between arc CG and arc DF. Mathematically, that looks like this:
and
44(2) = 160 - DF and
88 = 160 - DF and
-72 = -DF so
DF = 72 degrees, second choice down

Answer:
Dimensions of box
Length is 12 feet
Width is 3 feet
Step-by-step explanation:
Let's assume length of sandbox is L
width of box is W
we are given
A rectangular sandbox has a width that's 1⁄4 of its length
so, we can write as

we know that
area = length*width
so, we get

now, we can plug back W

we can set Area=36

now, we can solve for L


now, we can find W


So, dimensions of box
Length is 12 feet
Width is 3 feet
