Question

Find the length of the third side. If necessary, round to the nearest tenth.

Answer 1

Answer:

4.5

Step-by-step explanation:

To find the hypotenuse of a right triangle, we use Pythagorean's Theorem which states that $a^{2}+b^{2} =c^{2}$. Plugging in the values of the two legs given, we get $2^{2} +4^{2} =c^{2} =20$. We can take the square root of each side and get that $c=\sqrt{20} =4.5$.
