The other leg is 12cm long.
Step-by-step explanation:
Given,
Hypotenuse = c = 15cm
One leg = a = 9cm
Other leg = b
As the triangle is right angled, therefore, using Pythagoras theorem;
![a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2%5C%5C%289%29%5E2%2Bb%5E2%3D%2815%29%5E2%5C%5C81%2Bb%5E2%3D225%5C%5Cb%5E2%3D225-81%5C%5Cb%5E2%3D144%5C%5C)
Taking square root on both sides;
![\sqrt{b^2} =\sqrt{144} \\b=12\ cm](https://tex.z-dn.net/?f=%5Csqrt%7Bb%5E2%7D%20%3D%5Csqrt%7B144%7D%20%5C%5Cb%3D12%5C%20cm)
The other leg is 12cm long.
