Which side lengths form a right triangle? choose all answers that apply: choose all answers that apply: (choice a) a 2, 2, \sqrt42,2, 4 ? (choice b) b 9, 40, 419,40,41 (choice c) c \sqrt5, 10, \sqrt{125} 5 ? ,10, 125 ? stuck? watch a video or use a

(B)

Step-by-step explanation:

The given options are:

A. 2, 2,

B. 9,40, 41

C.

In order to prove that the given side lengths form a right triangle, we will satisfy the Pythagoras theorem.

A.

⇒

⇒

which does not satisfy the theorem, thus this option is incorrect.

B.

⇒

⇒

which satisfies the theorem, thus this option is correct.

C.

⇒

⇒

which does not satisfy the theorem, thus this option is incorrect.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
