Use Pythagorean theorem to solve the following problems.
katovenus [111]
The Pythagorean theorem tells you that for legs a and b, and hypotenuse c this relationship holds:
  c² = a² + b²

It can be useful to make a couple of rearrangements of this relation.
  c = √(a² +b²)
  a = √(c² -b²)

1. c = √(10² + 8²) = √164 = 2√41

2. a = √(26² - 10²) = √576 = 24

_____
It doesn't matter which leg you call "a" and which one you call "b", unless they are specifically marked on the triangle. Then use the marks you are given.

Help me please! will mark brainliest if ur correct!
Zina [86]

Answer:

i think it's c

Step-by-step explanation:

ok so i think i get it, volume is width*length*depth so dividing the known volume by its width gives you the length*depth.

after that set up a porportion:

(L*W)of known/92 = x/46

solve for x gives you the length*depth of the unknown volume, times that but the 46 width.. i got 60

i think that's right but im not a teacher or anything
