What is the measure of one angle in the regular decagon?

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1440 degrees (from above)... And there are ten angles... So, the measure of the angle of a regular decagon is 144 degrees.

Step-by-step explanation:

∠cbe and ∠deb are same-side interior angles.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
