Use a straight edge and a protractor to construct an acute angle of 65 degrees
A 40 degree acute angle can be constructed with a straight edge and a protractor.
Describing the process in words is much more difficult than doing it. So I suggest you sketch out the steps as described. It will be much clearer that way! 1. Start with a straight East-West line. 2. Draw a line perpendicular to it - this will be North-South. 3. Now bisect the angle between West and South. This line will run from the centre to the SouthWest! 4. The angle between the line going East and this last line is 225 degrees.
Use a protractor.

You'll also need a protractor to construct a 220 degree angle which can then be bisected by means of a compass and a straight line to form two 110 degree angles.
