The sum of all three internal angles is 180 degrees so, if two of them are 40 degrees each the third must be ...
96 degrees
The three angles always add to 180, so the third angle would be 40 degrees.
If you mean the equal angles were each 70o then 180 - 140 ie 40o
60 degrees
The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees
Well, honey, the sum of all angles in a triangle is 180 degrees. So if two angles are already 54 degrees each, the third angle would be 72 degrees to make up the total. It's basic math, darling.
180- total of the first two angles= 3rd angle
90 degrees
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
96 degrees
The three angles always add to 180, so the third angle would be 40 degrees.

55Improved Answer:-It is: 180-54-54 = 72 degrees
If you mean the equal angles were each 70o then 180 - 140 ie 40o
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
60 degrees
