Jordan measures the side lengths of a triangular piece of sheet metal. the side lengths are 156 cm, 133cm, and 205 cm. verify that the triangular piece of sheet metal is a right triangle. (this problem involves polynomial identities)
as soon as possible,

see the explanation

Step-by-step explanation:

we know that

If the triangular piece of sheet metal is a right triangle, then the side lengths must satisfy the Pythagorean Theorem

so

where

c is the hypotenuse (the greater side)

a and b are the legs of triangle

we have

substitute

----> is true

so

The side lengths satisfy the Pythagorean Theorem

therefore

The triangular piece of sheet metal is a right triangle

i do not know the answer i am sorry

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
