Answer:

height = 28 feet

Use triangle ABC below to answer the question that follows:
AnnyKZ [126]

Answer: Choice 1) The sum of the angles A and B are supplementary to angle C


Why is this the answer? Because we'll use facts 2 through 4 to help prove the triangles similar. If fact 2 is true, then fact 3 leads to helping set up the congruent corresponding angles (either A = D or C = E). Fact 4 is true because all angles are congruent to themselves, and this fact is the other angle pair we need to prove the triangles similar.


We don't use fact 1 even though it's a true statement. The fact that A+B+C = 180 isn't really useful to compare across two triangles.

What is the volume of the prism
MakcuM [25]

From the graph , we have to find the length, width and height of the prism to calculate volume .

And for that we have to use distance formula.

Length= \sqrt{(4-4)^2 +(6-0)^2 + (0-0)^2 } = \sqrt{36} =6 \\ Width = \sqrt{(4-0)^2+(6-6)^2+(0-0)^2} = \sqrt{16}=4 \\height = \sqrt{(4-4)^2 +(6-6)^2 +(2-0)^2 } = \sqrt{4} =2

And the formula of volume is

Volume = length * width * height =  6*4*2=48 \ cubic \ units
