We are given a? + b2 = c2 for ABC and right
ADEF constructed with legs a and b and hypotenuse
n. Since ADEF is a right triangle, we know
that a² + b2 = n2 because of the
V. By substitution, c? = n2 Using
the square root property and the principle root, we can
take the square root of both sides to get
c=n. By
M. triangles
ABC and DEF are congruent. Since it is given that
F is a right angle, then 2 is also a right angle by
CPCTC. Therefore, ABC is a right triangle by

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
