Victor has 100 trading cards, each with a distinct power level between 101 and 200 inclusive. Whenever he heads out, he alwaysrandomly selects 21 cards to bring with him just in case he meets a fellow collector. Prove that no matter which 21 cards he brings, Victor will always be able to select 4 of those cards that exhibit the following property: Let the average power level of all 4 cards bep. The cards can be split into two pairs, each of which also has an average power level of p.

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

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.
