In a triangle, the three interior angles always add to 180°

5x + 7x + 8x = 180
20x = 180
x = 180/20
x = 9

m∠1 = 5x = 5*9 = 45°

m∠2 = 7x = 7*9 = 63°

m∠3 = 8x = 8*9 = 72°

Answer:
45°, 63° and 72°

Which measurements for the capacity of the ice cream carton?
nalin [4]

Answer:

  • 1 cup
  • 1 gallon

Step-by-step explanation:

In retail grocery stores in the US, you can find ice cream packaged in sizes of 1 cup (half pint), 1 pint, 1 quart, 1/2 gallon, 1 gallon, and perhaps some odd sizes in between. For commercial purposes, ice cream may be packaged in tubs of 3- or 5-gallons or more.

1 teaspoon would be an unusually small size, and 1 mL is about 1/5 of a teaspoon. These quantities are somewhat smaller than would be considered a "serving" of ice cream, so would generally be of little practical use.
