What is the length of a hypotenuse of a triangle if each of its legs is 4 units

azamat

Answer:

$\boxed{c = 5.7 units}$

Step-by-step explanation:

Using Pythagorean Theorem:

=> $c^2 = a^2+b^2$

Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)

=> $c^2 = 4^2+4^2$

=> $c^2 = 16+16$

=> $c^2 = 32$

Taking sqrt on both sides

=> c = 5.7 units
