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°}
Answer:
-271
Step-by-step explanation:
The value would be $2.53 million.
Set up a proportion to solve this:
7.6/78 = x/(78-52)
[7.6 million for 78 years; x million for 78-52 years remaining]
Cross multiply:
7.6(78-52) = x*78
7.6(26) = 78x
197.6 = 78x
Divide both sides by 78:
197.6/78 = 78x/78
2.53 = x
(3+a+2) (a+2-3)
(5+a) (a-1)
5a-5+a^2-a
Rearrange and combine like terms
a^2 +4a-5
