Question

Say you have a right triangle with side a = 21 and side b = 220. What is the length of side c?

Answer 1

Use the pythagorean theorem. \[a^2 + b^2 = c^2\]

Answer 2

\[21^2 + 220^2 = c^2\]

Answer 3

\[441 + 48400 = c^2\]

Answer 4

\[48841 = c^2\]

Answer 5

\[c = \sqrt{48841}\]

Answer 6

\[c = 221\]

Answer 7

That makes so much more sense now thank you (: I loved how you broke it down too it really helped, thanks again (:
