Answer:
25 gallons
Step-by-step explanation:
Let x be the number of gallons of orange juice worth $1.70 per gallon, then x gallons are worth $1.70x.
If 100 gallons of orange juice worth $2.20 per gallon, then 100 gallons are worth 
Total cost is

Together we will get x + 100 gallons of a mixture. This mixture we will sell for $2.10 per gallon, so, x + 100 gallons of mixture is worth $2.10(x + 100).
Thus,
![1.70x+220=2.10(x+100)\\ \\17x+2,200=21(x+100)\ [\text{Multiplied by 10}]\\ \\17x+2,200=21x+2,100\\ \\17x-21x=2,100-2,200\\ \\-4x=-100\\ \\4x=100\\ \\x=25](https://tex.z-dn.net/?f=1.70x%2B220%3D2.10%28x%2B100%29%5C%5C%20%5C%5C17x%2B2%2C200%3D21%28x%2B100%29%5C%20%5B%5Ctext%7BMultiplied%20by%2010%7D%5D%5C%5C%20%5C%5C17x%2B2%2C200%3D21x%2B2%2C100%5C%5C%20%5C%5C17x-21x%3D2%2C100-2%2C200%5C%5C%20%5C%5C-4x%3D-100%5C%5C%20%5C%5C4x%3D100%5C%5C%20%5C%5Cx%3D25)
108 is the answer because a triangle has a total of 180 degrees and you only have 72 so far basically add 36+36 or 36*2 then since you have 72 subtract it from 180 and thats your answer
