180° (n - 2), where n is the number of sides.
get a protractor, then multiply your decimal by 360 degrees. Then take that number and find it with the protractor.
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
An acute angle.
A right angle measures 90 degrees
The "Far Arc Near Arc theorem" is used in finding the angle measures of a secant.
360/number of sides = each exterior angle
360/number of sides = each exterior angle
2340 degrees(formula= 180(s-2)*s=sidesTHAT^^^^ ANSWER IS WRONG.The formula for finding the measure of an interior angle of a polygon is180 (n-2)/n.SO, 180(15-2)/15180(12)/152160/15Your answer is....144 degrees.
Doesn't work that way, sorry.
The study is called trigonometry.
An angle is a measure of how two lines meet each other. An angle by itself does not have an 'area'.
The formula is (n-2)x180 over n =x
Providing that it's a regular polygon: 360/number of sides = each exterior angle
It tells you how many triangles can be made using the figure. For example: A rectangle has 4 sides. The formula for angle measures is (n-2)180. Plug in 4 for n number of sides. (4-2)180 2(180) 360 degrees for all sides 90 degrees for one side
180° (n - 2), where n is the number of sides.
15 degrees is not a special angle, but it is half of 30, which is a special angle. If you need sin 15 you can use the half angle formula with 30 degrees.
