The two legs of a right triangle are the same length. the hypotenuse is 7 meters long. find the length of the legs. express your answer in simplified radical form, or as a decimal rounded to four places.

let

x> the length side of the legs of a right triangle

H> hypotenuse

we /know that

in a right triangle

Applying the Pythagorean Theorem

H²=x²+x²>H²=2x²> solve for x> x=H/√2

H=7 m

so

x=7/√2>(7√2) /2 m> 4.9497 m

the answer is

in simplified radical form> (7√2) /2 m

as a decimal rounded to four places>4.9497 m

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%
