In the game of roulette, the wheel has slots numbered 0, 00, and 1 through 36. A

metal ball is allowed to roll around a wheel until it falls into one of the numbered

slots. You decide to play the game and place a bet on the number 17. What is the

probability that the ball will land in the slot numbered 17 two times in a row?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Dis the correct answer
