Gian is allowed to spend 45 minutes on the computer after dinner. He spends his entire 45 minutes either watching videos or playing games.
Write an equation for the number of minutes Gian spends playing games, y, if he spends x minutes watching videos. I need help on were to graph the numbers.

where are the options?

step-by-step explanation:

a. is correct

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.
