Sum = 180(n-2)

S = 180(11 - 2)

S = 180(9)

S = 1620º

Hope this helps!

the sum of all interior angles in a polygon is

180( n - 2), where n = "number of sides".


now, this is an 11-gon, so the sum is

180( 11 - 2)

180(9)

1620.

Help ASAP!!!<br><br> Identify the correct trigonometry formula to use to solve for x.
Alex787 [66]

Answer:

cos(55) = 11/x

Step-by-step explanation:

We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
