Most of the time when you try to find a missing length of a right triangle you use Pythagorean theorem. Pythagorean theorem is A squared plus B squared equals C squared. C squared is always going to be the longest length/diagonal line otherwise known as your hypotenuse. In this case the ladder is the hypotenuse. So instead of adding five squared +20 squared you’re going to square 20 and then subtract five squared to get the missing length which would be B squared and then you have to find the square root of B squared. So 20 squared is 4000. 5squared is 25 400-25 = 375 square root of 375 is about 19.4.

Answer:
<em>There are 21 jelly beans in the jar.</em>
Step-by-step explanation:
Suppose, the number of jelly beans in the jar is
Two were off by 2, two were off by 3, two were off by 4. That means, the six guessed number will be:
Given that, Alice guessed 25; Betty, 18; Clare, 23; Dotty, 19; Edith, 24; and Fran, 17.
So, the sum of all six guessed number will be:
Thus, the equation will be..........
So, the number of jelly beans in the jar is 21.
