The measure of a single internal angle of any regular polygon is equal to 180 (n - 2) / n. Therefore, an internal angle of a regular icosikaiheptagon (27-sided polygon) is equal to 13.3 recurring, or 13 and one third, degrees.
It thereby follows that a measure of the external angle of the same polygon is equal to 180 - 13 and one third = 166.6 recurring, or 166 and two thirds, degrees.
A = 60 B = 20 C = 140 This can have a large number of answers.
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95

angle with the greatest measure
An acute angle
the measure of an angle is the degrees of an angle.
you can measure a angle with a protracte.
they both measure the angle in degrees
The measure of the obtuse angle would then be double that of the acute angle.
The measure of the exterior angle.
No cheating!
