Question

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

Answer 1

base of a triangle = 12cm

perpendicular of a triangle = 9cm

so,

hypotenus = √(base) ² + (perpendicular) ²

=√(12)² + (9)²

= √144+81

=√225

=15cm

Answer 2

Answer:

$a {}^{2} = b {}^{2} + c {}^{2}$

$a {}^{2} = 144 + 81$

$a {}^{2} = 225$

a = 15

length of hypotenuse = 15
