It is angle RST.
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!

What does a straight angle measure?
If it is a regular nonagon, then you use the following formula: [(s-2) x 180]/s = angle of one interior angle. (s means the number of sides) Then solve: [(s-2) x 180]/s = [(9-2) x 180]/9 = [7 x 180]/9 = 1260/9 = 140. Then, for the exterior angle, subtract 140 from 360. The measure of the exterior angle of a regular nonagon is 220.
105 degrees
The measure of angle P is 90 degrees.
