) For a company picnic, Robert ordered a box of fresh-baked gingerbread cookies and sugar cookies. The box included a total of 100 cookies, and 30% of them were gingerbread.
How many gingerbread cookies did Robert get?

30 gingerbread cookies.

Step-by-step explanation:

100 x 0.3 = 30

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 90 hope this
