In the left triangle, the measure of the hypotenuse is missing. Use the Pythagorean theorem to solve for the missing length.
-
Replace the variables in the theorem with the values of the known sides.
482 + 142 = c2
-
Square the measures and add them together.
The triangle on the right is missing the bottom length, but you do have the length of the hypotenuse. It doesn't matter whether you call the missing length a or b.
-
Replace the variables in the theorem with the values of the known sides.
332 + b2 = 1832
-
Square the measures, and subtract 1,089 from each side.
-
Find the square root of each side.
