What is the formula for the area of a pentagon?
180° (n - 2), where n is the number of sides.
What is the formula for finding an angle in a circle graph?
get a protractor, then multiply your decimal by 360 degrees. Then take that number and find it with the protractor.
What is the sum of the interior angle measures of a 25 - sided polygon?
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.
What angle measures 88?
An acute angle.
What is the angle of a right angle?
A right angle measures 90 degrees
How to find angle measures of a secant?
The "Far Arc Near Arc theorem" is used in finding the angle measures of a secant.
What is the sum of the interior angle measures of a 15-sided polygon?
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.
What is the formula on finding each exterior angle of a regular polygon?
360/number of sides = each exterior angle
What is the formula for finding the measure of an exterior angle in a regular polygon?
360/number of sides = each exterior angle
What is the algebrically formula for finding the fourth angle?
Doesn't work that way, sorry.
What is finding all missing side lengths and angle measures of a right triangle?
The study is called trigonometry.
What a formula for finding area of angles?
An angle is a measure of how two lines meet each other. An angle by itself does not have an 'area'.
What is the formula used to find the sum of the angle measures in an n-gon?
The formula is (n-2)x180 over n =x
What is the formula in finding the measure of a exterior angle?
Providing that it's a regular polygon: 360/number of sides = each exterior angle
Why do you subtract 2 from the number of sides when finding angle measures?
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
What is the formula for the area of a pentagon?
180° (n - 2), where n is the number of sides.
How can half angle identities help solve nonspecial angle measures?
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.
