Question

Find the length of the hypotenuse of a right angled triangle whose perpendicular and base are 5cm and 12cm respectively.

Answer 1

for a right angled triangle,
(hypotenuse)^2 = (perpendicular)^2 + (base)^2
(hypotenuse)^2 = (12)^2 + (5)^2
(hypotenuse)^2 = 144+25
(hypotenuse)^2 = 169
hypotenuse = sqrt(169) =13
