Irrational because it keeps going on and on but doesn’t repeat
Answer:
If you take the 2 smallest sides and put it in the pythagreon theorem to get the other side length.
Step-by-step explanation:
So if you have a triangle with side lengths, 3, 4, and 5, you can use the exact equation below.

Because this is true, then the triangle does have a right angle.
Answer:
1) The value of
is 12.
2) The length of the diagonal is 49.
Step-by-step explanation:
1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:
(1)
We need some algebraic handling to determine the value of
:


![[5+(-2)] \cdot x = 36](https://tex.z-dn.net/?f=%5B5%2B%28-2%29%5D%20%5Ccdot%20x%20%3D%2036)


The value of
is 12.
2) If we know that
, then the length of the diagonal (
) is:


The length of the diagonal is 49.
Answer:
You do length times width times hight
Step-by-step explanation:
So mutliply 6 times 20 times 4 to get your answer
