Answer:
11
Step-by-step explanation:
All angles on a triangle equal 180. 80+60=140.
Now to solve for x, we set it to equal 40 for 180-140.
40=3x+7. 40-7=33
33=3x 33/3=11
x=11
The area of a hexagon is
A= a^2 (3√3)/2
we replace a with 4
A=41.57
The closest would be 7
7x7 is 49 and that is the closest
