Find The Measure Of Each Exterior Angle Of A Regular Triangle. As you get back to point A you have changed direction 9 times for a total angle in degrees of. Find the measure of each exterior angle in degrees of a regular polygon of n sides for the following values of n.
Sum of all exterior angles360 degrees. To solve we use the fact that W X Y. Now divide that by the 45 angles to find the measure of one interior angle.
The sum of the interior angles is given by this formula.
He shows the formula to find it which is 360n where n is the number of sides of the regular polygon. If the measure of the exterior angle is 3x - 10 degrees and the measure of the two remote interior angles are 25 degrees and x 15 degrees find x. Each angle of an equilateral triangle is of 60. When you are drawing a polygon at each vertex to turn the corner you have to change direction by a certain angle.
