40 degrees
30° Right angle = 90° One third of 90 is 30.
210 degrees
The third angle of what shape?
120 degrees
A right angle is 90 degrees, so one third of a right angle is 30 degrees.
30° Right angle = 90° One third of 90 is 30.

The three angles of a triangle add to 180 degrees. If two of them add to 140 degrees then the third must be 180 - 140 = 40 degrees.
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
180 - ( 80 + 60 ) = 40 the answer would be 40 degrees
A right angle is 90 degrees, so one-third of a right angle would be 30 degrees.
It is: 1/3 of 360 degrees = 120 degrees
60 degrees
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
