Answer:
x = 10
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠CBD is an external angle of the triangle, thus
4x + 30 = 2x + 10 + x + 30, that is
4x + 30 = 3x + 40 ( subtract 3x from both sides )
x + 30 = 40 ( subtract 30 from both sides )
x = 10

Okay. So, Marianna has 16 yards of fabric. Subtract 2 2/3 from 16, because those are the leftovers. 16 - 2 2/3 is 13 1/3. 13 1/3 / 3 1/3 is 4. Mariana made 4 pieces of 3 1/3 yard fabric. The answer is C: 4.
