Find the exact length of the third side

The length of the third side is 34.

Step-by-step explanation:

We use the Pythagorean theorem which says that for a right triangle with sides and , the hypotenuse is given by the equation:

In our case

So we have:

Which is the third side: the hypotenuse.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
