The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
180- total of the first two angles= 3rd angle
If two angles of a triangle each measure 55 what is the measure of the third angle?

...a right triangle.
Two of the angles measure 30 and 45. Thus, third angle = 180 - (30+45) = 180 - 75 = 105
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).
The missing angle measure is 100 degrees.
180- total of the first two angles= 3rd angle
If two angles of a triangle each measure 55 what is the measure of the third angle?
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.
In a triangle, the sum of all three angles is always 180 degrees. If two angles measure 32 degrees each, their total is 64 degrees. To find the measure of the third angle, subtract 64 from 180, which gives you 116 degrees. Therefore, the measure of the third angle is 116 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.
