Jessica, Neil, and Ryan are working together to decorate the school gym for the Winter Wonderland Dance. The following equation can be used to find h, the number of hours it will
take them to finish decorating the gym.
h/3+h/4+h/4=1
How long will it take Jessica, Neil, and Ryan to decorate the gym?
Write your answer as a whole number or as a fraction or mixed number in lowest terms.

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.
