sometimes,, you can have an odtuse angle 85 degrees and acute 23 degrees which is a total 108 degrees.
The sum of the exterior angles of a polygon add up to 360 degrees.
Two right angles (90 degrees each) equal 180 degrees (a straight angle).
Well, honey, the sum of angles in a triangle is always 180 degrees. So, if you already have angles measuring 45 and 85 degrees, just subtract their sum from 180 to find the measure of the third angle. In this case, the third angle would be 50 degrees. Easy peasy lemon squeezy!
Yes. A triangle has 180 degrees total, so if one of them is a right angle, which means it is 90 degrees, the sum of the remaining two angles is 180-90=90 degrees.
