A dairy needs 258 gallons of milk containing 7% butterfat. How many gallons each of milk containing 8% butterfat and milk containing 2% 2 % butterfat must be used to obtain the desired 258 258 gallons?

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

280 degrees

step-by-step explanation:

first, take -800 and add it to 360 until you get a positive number
