Question

find the length of hypotenuse of a right angle triangle .if remaining sides are 9 cm and 12 cm

Answer 1

Answer:

By Pythagoras theorem

(hypotenuse)^2 = (9)^2 + (12)^2

= 81 + 144

= 225

= 15

Answer 2

Answer:

Using Pythagoras Theorem

( Hypo. )² = ( Base )² + ( Height )²

Given ,

9 cm ( Base )

12 cm ( Height )

( Hypo. )² = ( 9 cm )² + ( 12 cm )²

( Hypo. )² = 81 cm + 144 cm

( Hypo. )² = 225 cm

( Hypo. ) × ( Hypo. ) = 15 cm × 15 cm

Hypotenuse = 15 cm
