The formula in finding the sum or the total measure of the interior
angles of polygon having n sides is:
Sum of interior angles = (n – 2) 180
Where n = number of sides of the polygon
In this problem, you are asked for the sum of the interior
angles of a 17 sided polygon. You have to substitute the number of sides to the
formula:
Sum of interior angles = (17 – 2) 180
Sum of interior angles = (15) 180
Sum of interior angles = 2,700 degrees
Answer:
(x² - 9)(x² - 2) = 0
x = 3 or √2
Step-by-step explanation:
To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial. In this case the polynomial
can be factored into:
(x² - 9)(x² - 2) = 0
Setting each of these expressions equal to '0':
x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3
x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2

- Line YZ should be drawn parallel to PQ
<h3 /><h3>What are the lines parallel to each other</h3>
YZ is drawn parallel to PQ through the point R
<ZRP + <PRQ + <QRY = <ZRY
<ZRP = <RPQ [YZ // PQ]
<QRY = <PQR [YZ // PQ]
From the above,
<PQR + <RPQ + <PRQ = <ZRY =
