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.

Answer:
<em>2.34248 × 10^-4</em>
Step-by-step explanation:
to subtract in scientific notation, you have to make the exponents equal to each other first. To do that, move the minuend's decimal point to the right.
moving decimals to the left will add 1 everytime you move it.
moving decimals to the right will subtract 1 everytime you move it.
(-4) - 3 = (-7) ← the minuend now becomes 2350 × 10^-7
Now that the exponents are equal, subtract normally.
(2350 × 10^-7) - (7.52 × 10^-7) = 2342.48 × 10^-7
scientific notations should always be in between the numbers 1 and 10, therefore, you have to move 2342.48's decimal to the left. Remember that you have to add the amount of times you moved the decimal place to the exponent.
= 3 + (-7) → -4
final answer = 2.34248 × 10^-4
