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.
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 105 degree angle is equal to 180 - 105 = 75 degrees.
105 degrees
180-75=105 degrees
In conjunction with a straight edge and a protractor
A 75 degree angle.

Yes
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 105 degree angle is equal to 180 - 105 = 75 degrees.
105 degrees
.105
With a protractor and a straight edge
The supplement of a 75-degree angle is the angle that, when added to 75 degrees, equals 180 degrees (a straight line). To find the supplement of a given angle, you subtract the given angle from 180 degrees. Therefore, the supplement of a 75-degree angle is 105 degrees.
Easiest is to use a protractor. Alternative: Draw a 90 degree angle. Bisect the external angle so that it is 45 degrees. Trisect that angle so that the angle adjacent to the 90 degree angle is 15 deg Then 90 + 15 degrees = 105 degrees. Both, bisection and trisection require the use of a compass (and ruler).
180-75=105 degrees
Half 3
An angle of 105 degrees is an obtuse angle.
