a%5E2%2Bb%5E2=c%5E2 Start with Pythagorean's Theorem


a%5E2%2B2%5E2=%28sqrt%2829%29%29%5E2 Plug in b=2 and c=sqrt%2829%29


a%5E2%2B4=29 Square 2 to get 4. Square sqrt%2829%29 to get 29

a%5E2=25 Subtract 4 from both sides

a=sqrt%2825%29 Take the square root of both sides


a=5 Simplify

Answer:

So the length of the missing side is a=5
