<span>Each Interior Angle / 180 = <span>(N -2) <span>/ (N)
144 / 180 = (n-2) / n
144 * n = 180n -360
360 = 36 n
n = 10 the number of sides

The answer should be 339.1
Answer: 52.489…
Step-by-step explanation:
Angle of elevation is 58 degrees, and the opposite value is 84 feet, so you’re lookin g for adjacent. That means you’ll use tangent to solve this equation:
Tan(58)=84/x
5/3*-3*9/18
5*-9/18
-45/18
-2.5

Answer:</h2>
Four points are always coplanar if:
A. They lie in the same plane.
C. all of them are collinear.
<h2>
Step-by-step explanation:</h2>
<u>Coplanar--</u>
The points are said to be coplanar if all of them lie in the same plane.
<u>Collinear-</u>
The points are said to be collinear if all of them lie on a straight line.
Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.
Hence, we may say that Four points will be coplanar if all of them are collinear.
Hence, the correct options are:
Option: A and Option: C
