Question

Find the hypotenuse of a right triangle if side a=3 and side b=4​

Answer 1

5 units

Explanation:

By Pythagoras theorem:

`(hypotenuse)^2 = a^2+ b^2\\\therefore hypotenuse = √(a^2+ b^2) \\\therefore hypotenuse = √(3^2+ 4^2) \\\therefore hypotenuse = √(9+ 16) \\\therefore hypotenuse = √(25) \\\therefore hypotenuse = 5\: units`
