The missing angle measure is 100 degrees.
77. The sum of the three angles in a triangle equal the sum of 180 degrees
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
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.
Two angles of a triangle add up to 65°. What is the measure of the third angle?

The missing angle measure is 100 degrees.
100.
The third angle is (128 degrees) minus (the second angle).
If that's a triangle, the third angle is 90 degrees.
The interior angles of a 2-D triangle will always add up to 180 degrees. To determine the measure of the third angle: 180 - (32 + 75) = 73 degrees
The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
77. The sum of the three angles in a triangle equal the sum of 180 degrees
The third angle measures 18 degrees.
