First you need to find the sum of all the interior angles using the formula (n-2)*180, where n is the number of sides.
There are 6 sides to this figure so the interior angles need to equal (6-2)*180 = 4*180 = 720.
Now add all the given angles together: 2x + 3x + 3x + 3x +3x +2x = 16x
Now we know 16X = 720
Find X by dividing both sides by 16:
X = 720 / 16
X = 45
Now we know X, so to find E, replace X with 45 and multiply by 3:
3X = 3(45) = 135.
E = 135. The answer is D.
Last month, my house used 1,740 kilowatt-hours of electrical energy,
and the part of my bill that charged for the electricity was $226.20 .
For the same month, my brother in Boston used 1,175 kilowatt-hours
of energy, and the energy part of HIS bill was $199.75 .
Which of us gets the better deal on his electrical energy ?
