Aright triangle has a base of 16 meters and a height of 12 meters. use the pythagorean theorem to find the third side.

20 meters

Step-by-step explanation:

Write out and then apply the Pythagorean Theorem, a^2 + b^2 = c^2:

16^2 + 12^2 = hypotenuse^2:

256 + 144 = 400 = hypotenuse^2

The length of the third side is the length of the hypotenuse, which in turn is 20 meters.

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%
