A total of 50 students are in band or in choir 18 students are in the band
22 students are in the choir

15 students are neither in th band or choir

what is the probability that a random selected student is in the band and choir​

the answer is 8

step-by-step explanation:

3.14 x 8x8

answer: i don't understand it

step-by-step explanation: sorry

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.
