Easy
In a right triangle, the two legs measure 120 cm and 22 cm. Find the length of the hypotenuse.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 120² + 22² = 14400 + 484 = 14884 = 122², confirming the sides 120, 22, 122 form a right triangle so the hypotenuse is 122 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
