If you're talking about a triangle, the third angle is 80 degrees.
30 degrees
Two complementary angles add up to a right angle (90 degrees). If one of the angle is x, the other is 2x. So, x + 2x = 90 3x = 90 x = 30 Thus one of the angle is 30 degrees, and the other is 60 degrees.
1st angle = 30 degrees 2nd angle = 60 degrees
A right angle is 90 degrees, so one-third of a right angle would be 30 degrees.
The third angle is 30 degrees and it is an isosceles triangle.
If it's a right angle triangle then the the third angle is 60 degrees.
60 degrees. There are 180 degrees in a triangle.
60 degrees for an equilateral triangle but it depends on other types! Other angle measure could be 30, 45, or 90 degrees as well.
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
Two complementary angles add up to 90 degrees.If one is 30 degrees, the other has to be a 60 degree angle
30 150 and 150 (for a total of 360 degrees)
