Which of the following is an example of independent events a. two group of people are drawn successively without replacement from a group of 20 to represent the group b. drawing a queen from a standard deck of cards and then drawing an ace without replacing a queen. c. getting tails from a coin toss and drawing a king from a standard deck of cards d. selecting a bead from a bag of 6 different colored beads and then selecting a second bead without putting the first back.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
