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

...a right triangle.
Two of the angles measure 30 and 45. Thus, third angle = 180 - (30+45) = 180 - 75 = 105
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.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
180- total of the first two angles= 3rd angle
The missing angle measure is 100 degrees.
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.

...a right triangle.
96˚all angles to a triangle equals 180˚
180-39-77 = 64 degrees
If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.
