Answer:
im gonna say its 6 but im not so sure. But thats my closest answer
Step-by-step explanation:
So 3 2/3 is about 3.67 so it would go in between 3.65 and 3.7. So it would be the second answer.
Answer:
8.27
Step-by-step explanation:
subtracting a negative number creates a positive
two negatives = a positive
Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.
