Because GH bisects FGI, FGH=HGI
2x+1=3x-9
x=10°
so the measure of HGI is 21°
Answer: 30
Explanation:
There are 2 types of cones and 15 types of flavors. So there are 2*15 = 30 different combos of one-scoop ice cream orders.
Starting from what I know (the difference between ribbons), I decided to go from the bottom and work my way up. I then noticed a pattern (each sum was three more of the previous one), and decided to keep my pattern of the three numbers but not have to do any major mental work and instead add three to the previous sum until I got to 38.
The answer is c 10% of 89 is 8.9 so multiply by 3 you get 26.70
