In a right triangle, the hypotenuse measures 116 cm and one leg measures 80 cm. Find the length of the other leg.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 80² + 84² = 6400 + 7056 = 13456 = 116², confirming the sides 80, 84, 116 form a right triangle so the missing leg is √(116² - 80²) = √7056 = 84 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
