Yes by bisecting an angle of 140 degrees with a compass
To construct a 105-degree angle using a compass, start by drawing a straight line and marking point A on it. Next, use a compass to draw a 60-degree angle: place the compass point on A, draw an arc across the line, and label the intersection point B. Then, without changing the compass width, place the point on B and draw another arc to create a 60-degree angle above the line. Finally, draw a line from A through the intersection of the arcs, which will create a 105-degree angle with the original line.
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.
To construct a 54-degree angle with a compass, start by drawing a straight line using a ruler. Place the compass on one endpoint of the line and draw an arc that intersects the line. Without changing the compass width, place the compass on the intersection point and draw another arc. Where the two arcs intersect is a point that, when connected to the endpoint of the line, forms a 54-degree angle.
To draw an angle complementary to a 40-degree angle without a protractor, first draw a straight line using a ruler. Then, use a compass to mark a point on the line as the vertex of the angle. Set the compass to a width that can create an arc, and draw an arc that intersects the straight line, marking two points. Next, without changing the compass width, place the compass point on one of the intersection points and draw another arc above the line. Repeat this from the other intersection point, creating two arcs that intersect. Finally, draw a line connecting the vertex to the intersection of the arcs, which will give you a 50-degree angle, complementary to the original 40-degree angle.

To draw a 40-degree angle using a compass, start by drawing a straight line and marking a point on it as the vertex. Place the compass point on the vertex and draw an arc that intersects the line. Without changing the compass width, place the compass point on the intersection and draw another arc. Finally, adjust the compass to a width that corresponds to 40 degrees (using a protractor for reference), and draw an arc from the vertex to intersect the previous arc. Connect the vertex to this intersection to form the 40-degree angle.
To bisect an 85-degree angle, start by drawing the angle with its two rays. Next, place the compass point at the vertex of the angle and draw an arc that intersects both rays. Without changing the compass width, place the compass point at each intersection point and draw two arcs that intersect each other. Finally, draw a line from the vertex through the intersection of the arcs; this line bisects the 85-degree angle into two equal 42.5-degree angles.
To create an 85-degree angle with a compass, first draw a straight line (the base of the angle). Place the compass point on one end of the line and draw an arc that intersects the line. Without changing the compass width, place the compass point on the point of intersection and draw another arc. Measure 85 degrees using a protractor from the base line to mark the angle, then draw a line from the vertex to this mark to complete the angle.

Well, honey, you start by drawing a line with your ruler. Then, you put the point of your compass on one end of the line and draw an arc. Next, you put the point of your compass on where the arc intersects the line and draw another arc. Where those arcs meet is your 32-degree angle. Voila!
To construct a 175-degree angle using a compass, start by drawing a straight line and marking a point A on it. Place the compass point on A and draw a large arc across the line, marking the intersection point as B. Now, without changing the compass width, place the compass point on B and draw another arc above the line. Next, set the compass to a smaller width and draw an arc from A, creating an intersection point with the first arc above the line. Finally, connect point A to this intersection point to create the 175-degree angle.
