Answer:
So a triangle has to be 180° overall And that is an equilateral triangle therefore every angle is equal so every angle inside is 60° so ?=60° another way you can find this out is a straight line is equal to 180° and since you have the external angle which equals 120° you do 180°-120° and get 60° and the 180°-60°-60°=60° and that’s your mystery angle. I hope that’s not too confusing.

Alright well the Answer to this question is
9 Hope this helps :)
Step 1: Convert to mixed number 1 7/9 into an improper fraction first by multiplying the denominator, by the whole number
Step 2: Then add the numerator, to get the new numerator. Place the New numerator over the old denominator
16 divided by 16 and 9
To divide by fraction, multiply by it's reciprocal 16(9/16)
Cancel the common factor of 16, then simplify 1/1 9/1 which gives u

Step-by-step explanation:
We have no idea how much is one faithful of a barrel.
A solid line, because each lunch cost the same, and the price does not differ from lunch to lunch. So, 100 - 4 = 96 | 96 - 4 = 92, etc.
