Anew athletic shoe store had expenses of $40,000 for designing and building the shelves and counters and $120,000 for the first year’s shoe inventory. so far this year, the shoe sales are $70,000. what do the sales have to be for the rest of the year for the store to break even? a. $70,000

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.
