The hypotenuse of a right angle triangle is 15 cm. the sum of the legs of the triangle is 21 cm. Find the legs of the triangle.
How do I solve this?
Since the sum of the legs are 21 cm, one leg will be $\displaystyle x$ cm and the other will be $\displaystyle 21-x$ cm. By using Pythagoras' theorem you'll get $\displaystyle x^2+(21-x)^2=15^2$.
