Solve for the length of the unknown side in the following right triangle. (Side AC is the hypotenuse.) Round your answer to two places, where applicable.

Side BC=12
Side AC=19
Answered by MathMate
Given ABC is a right triangle with AC being the hypotenuse, then angle B is a right-angle.
Use Pythagoras Theorem to solve thus:
AC²=BC²+AB²
or
19²=12²+AB²
Solve for AB.
