Question

Find the length of the hypotenuse of a right triangle the other two sides of which measures 9cmand12cm

Answer 1

Answer:

Let △ABC be right angled at B

Let AB=12cm and BC=9cm

Hypotenuse (AC)=?

Then, by Pythagoras theorem

AC

2

=AB

2

+BC

2

AC

2

=12

2

+9

2

AC

2

=225

Sending power 2 from LHS to RHS it becomes square root

AC=

225

AC=15cm

The length of the hypotenuse of a triangle is 15cm
