Please help me i really need it geometry?

height= 30 area= 2160

Step-by-step explanation:

I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)

Then, to find area the formula is a=b*h

You already have the base in the image and you already calculated the height

Again, I don't know if this is right. It's not the same as how I do it here

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
