Question

Find the length of hypotenuse of a right angled triangle if remaining sides are 9 cm and 12 cm

Answer 1

In a right angled triangle,

According to pythagoras theorem .

$(Hypotenuse{)}^2=(base{)}^2+(Height{)}^2$

$=(9{)}^2+(12{)}^2$

$=81+144$

$=225$

$\therefore$ Hypotenuse = 15 cm

Hence, the length of the hypotenuse is 15 cm
