Question

please tell me answer ​

Answer 1

Answer:

Formula used-

(Hypotenuse) ² = (Base) ² + (Height) ²

Solution-

In a right angled triangle LMN ,∠N= 90° , Hence side LM is the Hypotenuse

According to Pythagoras Theorem, we get,

( LM )² = ( LN )² + ( MN )²

( LM )² = ( 15 )² + ( 20 )²

        

( LM )²  = 225 + 400

( LM )² = 625  -( Taking square root on both the sides )

LM = ✓625

∴LM = 25

Ans- The length of seg LM is 25 cm
