the sum of all interior angles in a polygon is
<h2>180( n - 2), n = number of sides</h2>
we know this one is a PENTAgon, so it has 5 sides, so the total for the interior angles will be
180( 5 - 2) = 540 degrees.
540° - 88° - 118° - 132° - 100° = 102° <- fifth angle.
Answer:
the answer to this question is 66
Answer:
gas = $0.23, electricity = $0.10
Step-by-step explanation:
D because the radical simplified is -sqrt of 6 / 3 and when you multiply D with the radical it gives you that answer.
Answer:
x cannot = 3 or -3; solution is x = 7/11.
Step-by-step explanation:
I believe you meant 6 / (x-3) + 5 / (x+3) = 10 / (x^2 - 9). Those parentheses are important, to avoid ambiguity.
Part A:
Then: x cannot be 3, as the first term would then be undefined.
Also: x cannot be -3, as then the 2nd term would be undefined.
Multiply all three terms by the LCD, which is (x-3)(x+3):
6(x+3) + 5(x-3) = 10
Performing the indicated multiplication,
6x + 18 + 5x - 15 = 10. Then 11x + 3 = 10, or 11x = 7, or x = 7/11.
This is the solution (Part B).
