Question

In right angel triangle sides making right angel are 9cm and 12cm find the length of hypotenuse

Answer 1

Answer:

15 cm

Step-by-step explanation:

Let the ∆ABC be a right angle triangle, right angle at B

Let AB and BC be the sides of ∆ABC and AC be hypotenuse

So,AB=9cm and BC=12cm

By Pythagoras theorem in ∆ABC

AB²+BC²=AC²

9² + 12²=AC²

AC²=81+144

AC²=225

AC=√225

AC=15cm

The length of Hypotenuse is 15 cm

Answer 2

SOLUTION:-

Given

• height = 12cm
• Base = 9cm

Answer

• hypotenuse = 15cm

To Calculate

• Length of hypotenuse __?

Step by Step Explanation

• height = 12cm
• Base = 9cm
• hypotenuse?

By Pythagoras theorem

hypotenuse² = perpendicular²+ Base²

putting values,

⟹ h²= 12²+9²

⟹ h²= 144+81

⟹ h²= 225

⟹ h = 15

Hence

• hypotenuse = 15cm
