Question

How do you find b in pythagorean theorem given a=3, c=4?

Answer 1

Plug in, and solve!

Explanation:

The Pythagorean theorem is: `a^2 + b^2 = c^2`.
So, we can plug in the given values (a = 3, c = 4), and solve for b.

`3^2 + b^2 = c^2`
`9 + b^2 = 16`
`b^2 = 7`
`b = sqrt7`

It's straightforward, plug in the numbers you know, then solve!

If you are asked to give answers in square root form, make sure you completely rationalize your solution . If you are told to give your solution in decimal form, make sure to round to the appropriate place, if required.
