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.

With a straight edge and a protractor
Draw a straight line and place zero degrees of the protractor at the endpoint of the line then mark out 135 degrees and join the endpoint with the marked out degrees to construct the required angle.
