You can find out the degrees of the angles of shape shape by following these instructions.
First you line up the bottom line of the protractor onto a side of a shape. The corner of the shape should be on the tiny dotlike thing in the middle of the bottom line of the protractor. Next, you find out if the angle is obtuse (larger than a right angle), acute (smaller than a right angle), or right.
If it's obtuse, you know that it's larger than 90 degrees. You should look at the larger number the other line is pointing at.
If it's acute, find you the angle by finding out which number the other line is pointing at.
If you think it's a right angle, see if the line's pointing at another number. Otherwise, it's a right angle.
Using a protractor is the easiest formula
A 127.5 degree angle can be constructed by using a protractor and a straight edge.

With a straight edge and a protractor
You cannot, you must use a protractor.
In conjunction with a straight edge and a protractor
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
It is the line from 0 to 130 degrees on your protractor
To draw a 70-degree angle, start by drawing a straight line using a ruler; this will be one side of the angle. Place a protractor's center point at one end of the line, aligning the baseline of the protractor with the line. Locate the 70-degree mark on the protractor and make a small mark. Finally, remove the protractor and draw a line connecting the end of the original line to the mark you made, forming the 70-degree angle.
Unless you have some other source of information, your only option is to measure it - possibly using a protractor.
To draw a 65-degree angle, start by drawing a straight horizontal line using a ruler; this will be one side of the angle. Place a protractor on this line so that the center point of the protractor aligns with one end of the line. Find the 65-degree mark on the protractor and make a small mark above the line. Finally, remove the protractor and use a ruler to draw a line from the end of the original line to the mark, forming the 65-degree angle.
