The length of the other leg is 5cm

By Pythagoras theorem we know that
#hypotenuse^2#= #Perpendicular^2#+#base^2#

Putting the values you will get
Other leg=#sqrt(13^2-12^2)#=5cm
Hope this answer helps 😁

#5#

Using the Pythagorean Theorem, the square of the hypotenuse is equal to the sum of the squares of the sides.

#h^2 = a^2 + b^2#
#13^2 = 12^2 + b^2#
#169 - 144 = b^2# ; #25 = b^2#; #b= 5#
