Answer: you can use Pythagorean theorem
, which formula is , "a" and "b" are the sides, and "c" is the hypotenuse (the longest side, the side opposite to the 90 degree angle)
<em>Example:</em>
If they give that one side is 2 inches and the other side is 4 and you need to find the hypotenuse it would be like this:
1) plug the numbers to the formula
2) solve the exponents of the numbers given (not the letter, in this case "c")
16 + 36 =
3) combine like terms (in this case 16 +36)
52 =
4) Finally, Find the square root of "c" to remove its exponent and do the same to the other side, in this case 52)
(square root of 52 rounded to the nearest hundred is 7.21)
7.21 = c
<h3><u><em>So 7.21 is your missing side in this example</em></u></h3><h3>look up Pythagorean theorem Khan Academy</h3>
