Question

In a right angled triangle sides making right angle are 9cm and 12cm find the length of the hypotenuse ​

Answer 1

Answer:

Hypotenuse= 15cm

Step-by-step explanation:

a^2+b^2=c^2

9^2+12^2=c^2

225=c^2

c=15

Answer 2

Given :-

• In a right angled triangle sides making right angle are 9cm and 12cm

 

To Find :-

• Length of hypotenuse of that triangle.

Solution :-

~Here, we’re given the length of base and perpendicular in a triangle, which are making right angle of 90 degrees and we need to find the hypotenuse of that triangle. We can find the hypotenuse by applying the Pythagoras theorem.  

_____________

As we know that ,

★ Pythagoras theorem = h² = b² + p²  

Where,  

• h is hypotenuse  
• b is base = 9 cm  
• p is perpendicular = 12 cm  

Finding hypotenuse :-

➟ h² = 9² + 12²  

➟ h² = 81 + 144  

➟ h² = 225  

➟ h = √225  

➟ h = 15 cm  

_____________

Hence,  

• Measure of Hypotenuse is 15 cm
