Philip is going on a 4,000-mile road trip with three friends. the car consumes 12 gallons of gas per 400 miles, and gas costs $2.50 per gallon. it’ll will cost philip and his friends $300 total for gas. if philip and his friends want to split the cost of gas evenly, how much should they each pay?

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.
