Answer 1

PLEASE MARK MY ANSWER AS BRAINLIEST

Step-by-step explanation:

This is a triangle with angles 45°,45°,90°

Their sides opposite to each angles are in the ratio 1:1:root2

That is , if we suppose NM=5cm

then NL=NM=5cm

LM=5 root 2

The lengths can be also find by using pythagoras theorem as it is a right angled triangle.
