Question: Answer and explain the answer below. How many students are wearing a hat, but not a sweatshirt?

It is unknown because three of the students didn't survey so It could be no more than 3 because it says 7 students are wearing a sweatshirt, 3 students are wearing a hat and a sweatshirt, and 5 students are not wearing either a sweatshirt or a hat.

Hope it helps.

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.
