Right triangle abc is reflected over ac, then dilated by a scale factor of to form triangle dec. which statements about the two triangles must be true? check all that apply. △abc ~ △dec ∠b ≅ ∠e 3bc = 2ec 3de = 2ab 3m∠a = 2m∠d 2m∠a = 3m∠d

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*

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.
