The three angles in a triangle add up to 180. 38 + 27= 65. 180-65=115
No. The angles of a triangle always add up to exactly 180 degrees. A right triangle must have one right angle, i.e. an angle of 90 degrees. That leaves 90 degrees for the other two angles. 38 and 54 add up to 92 degrees, so they can't co-exist with the 90-degree angle in a right triangle.
180-38-95. The sum is always 180 in a triangle, so just subtract the other two from 180 to get the third.
The sum of the interior angles of an n-gon is found by the formula: (n-2)*(180) degrees. So a 38-gon would have (38-2)*(180) degree sum for its interior angles, which equals 6,480 degrees.
Well, darling, 38 plus 67 is 105. It's not rocket science, just basic addition. So go ahead and add those numbers up, unless you want me to do it for you too!
