With a protractor and a straight edge.
Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 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.
They are: 85 degrees and 175 degrees respectively
Hint: 90/2=...

Well, darling, an 85 degree angle is called an "acute angle." It's like a cute little angle that's smaller than a right angle but bigger than a straight angle. So, next time you come across an 85 degree angle, just remember it's acute and adorable.

It's supplement is 85 degrees.

Hint: 90/2=...
Supplement angles add up to one hundred eighty degrees, so the supplement of an eighty five degree angle would be a ninety five degree angle.

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.
