The​ Musicians' Guild, with 929 members, has 7 representatives on the National Arts Advisory Board​ (NAAB). The​ Artists' Alliance, with 817 ​members, has 5 representatives. If either the musicians or the artists can be given one additional representative to the​ NAAB, determine which group should get it using the steps in

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.

i think the answer is true

step-by-step explanation:

add 8+12 to get a simplified answer of 12r-20
