Answer:

c = 18

Step-by-step explanation:

Rewrite c / 3 equals 30 / 5 as:

 c       30

----- = -----

  3       5

Reduce 30/5 to 6/1:

 c        6

----- = -----

  3       1

Cross multiplying, we get 1c = 18, or c = 18.

Answer:

Unless there is more to the question than c = 2 because 30 /5 = 6 and if c is 3 than 3 = 6 so simplify if needed.

If you are not familiar with the Pythagorean theorem, I will write it below to remind you for your future mathmatical endeavours:

{a}^{2} + {b}^{2} = {c}^{2}

c is the hypotenuse, and a and b are the other two sides. The hypotenuse is the largest side of a triangle. In this example, a and b are equal to each other and c is equal to 2, so I'm going to convert b into a and do some math trickery here:

{a}^{2} + {a}^{2} = 4

2 {a}^{2} = 4

Basically, I swapped b with a and combined like terms. Then I just replaced c with 2, then squared it into 4.

All you have to do now is solve for a

Step 1 is to divide both sides by 2 to get:

{a}^{2} = 2

Then just square both sides:

a = \sqrt{2}

Now you know that the length of the sides are equal to the square root of 2.

Sorry if this was a bit rushed, I hate running out of time on these. If you have any questions on why I did something, ask away in the comments.

Find the volume.<br><br><br> 986 m3<br><br><br> 3,360 m3<br><br><br> 408 m3<br><br><br> 1,680 m3
Jobisdone [24]

Answer:

The volume is 1,680\ m^3

Step-by-step explanation:

we know that

The volume of a triangular prism is

V=BL

where

B is the area of the triangular base

L is the length of the prism

we have

B=\frac{1}{2}(28)(12)=168\ m^2

L=10\ m ----> perpendicular distance between the two triangular bases

substitute

V=(168)(10)=1,680\ m^3
