A quadrilateral has 4 vertices and the sum of the measures of the interior angles is 360 degrees. There cannot be 4 diagonals in a quadrilateral.
Answer: 
Step-by-step explanation:
This is a multiplication problem. You are multiplying 
by 4. This also means 4 divided by 3. They are both the same.
M<ABC = m<EBD = 36 (vertical angles)
78 - x + 36 + 3x - 10 = 180 (straight angle)
Now solve for x
78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
- 68 -68 (subtract 68 on both sides)
2x = 58
x = 29
Answer:
The answer is A) 379.9
Step-by-step explanation:
3.14(11^2)
3.14*11^2
3.14*(11*11)
379.94 if rounded to the nearest tenth it would be 379.9
