In a right triangle, the two legs measure 35 cm and 120 cm. Find the length of the hypotenuse.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 35² + 120² = 1225 + 14400 = 15625 = 125², confirming the sides 35, 120, 125 form a right triangle so the hypotenuse is 125 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
