1 cake needs 22 cups.
12 cakes need x cups.
1 * 12 = 12
22 * 12 = 264
You'd need 264 cups of flour.

Answer:
The answer to your question is x = 40°
Step-by-step explanation:
According to the picture we determine that the triangle to the right is isosceles so two of its angles are equal.
Remember that the sum of the internal angles in a triangle equals 180°
2x° + 100° = 180
- Subtract 100 in both sides
2x + 100 - 100 = 180 - 100
- Simplify
2x = 80
-Divide both sides by 2
2/2 x = 80/2
Simplify and result
x = 40°
Your hand looks nice...
Anyway, 11/4 is the answer
