Question

The length of the hypotenuse of a right triangle is 13 cm. If one of the side of
the triangle be 5 cm long, find the length of the other side..

Answer 1

Answer:

12 cm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagoras theorem to find the length of the side

hypotenuse^2 = side a^2 + side b^2

= 13^2 = 5^2 + a^2

= 164 = 25 + a^2

= a = $\sqrt{164 - 25$

= a = $\sqrt{144}$

= a = 12 cm
