The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees
180-39-77 = 64 degrees
80 degrees
The three angles always add to 180, so the third angle would be 40 degrees.
The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1
If two angles of a triangle each measure 55 what is the measure of the third angle?
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.
90o
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
