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