Answer:
7.81*10^11
Step-by-step explanation:
1.86*10^5=186,000
186,000*4,200,000=7.81*10^11
It is an empty set because as you may have noticed, these lines have the same slope which means that they are parallel lines and parallel lines never intersect (which means it doesn't have a solution set).

Answer:
Step-by-step explanation:
The given hexagon has interior angles
x,x,x, x/2, x/2, x/2 for a total of S1=4.5x.
We also know that the sum of interior angles of any polygon of n sides is
S2=180(n-2)
For a hexagon, S2 = 180(6-2) = 720°.
Equating S1 and S2
4.5x = 720
x = 720/4.5 = 160.
Therefore substitute x in the given angles to get
{160°,160°.160°,80°,80°,80°}
