You also need a straight edge.
Because of the poor graphic facility of this browser, the description is rather longer and sounds more complicated than it is.
In summary, you
- draw a 60 degree angle,
- bisect it, and then
- consider its supplement.
So here goes (it will be easier if you read and do it together).:
- Draw a straight line.
- Mark a point A on the line.
- With the compasses, draw a quarter circle arc that intersects the line at point B.
- Using the same compass setting, draw another large arc from B which intersects the first arc at point C (angle CAB will be 60 degrees).
- With the compass point now at C, and still using the same compass setting, draw another arc to intersect the last arc at D.
- Angle DAB is 30 degrees.
- If BA is extended (on the other side of A) to a point E, the angle DAE is 150 degrees.
You also need a straight edge.

How do you construct a 37.5 degree angle using ruler and compasses?
To construct a 37.5-degree angle using a ruler and compass, start by drawing a straight line and marking a point A on it. Then, construct a 60-degree angle at point A by drawing an arc from A, marking points B and C where the arc intersects the line, and connecting A to B. Next, bisect the 60-degree angle by placing the compass point on B, drawing an arc that intersects the angle, and marking those intersection points. Finally, draw a line from A through the intersection of the arcs to create a 30-degree angle, then bisect the 30-degree angle to obtain the desired 37.5-degree angle.

Is it possible to construct an angle measuring 7.5 degrees by using a compass and a straitedge?
Yes, it is possible to construct an angle measuring 7.5 degrees using a compass and straightedge. This can be done by first constructing a 15-degree angle, which is achievable through a combination of bisecting angles. By bisecting a 15-degree angle, you can obtain the desired 7.5-degree angle. This method relies on the principle that angle bisection is a fundamental constructible operation.

How do you construct 105 degree angle with using compass?
with compass.........at 90+60degree angle,,,,,,,,, * * * * * and 90 + 60 = 105??? You need to draw a 90 degree ange and bisect it to give a 45 deg angle. Then add a 60 degree angle. 45 + 60 = 105.
