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?

55°

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.

90o

The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 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

Also 45

The third angle measures 18 degrees.

...a right triangle.

45 degrees.

77. The sum of the three angles in a triangle equal the sum of 180 degrees

96˚all angles to a triangle equals 180˚

180-39-77 = 64 degrees

The third angle is [180-(32+70)] = 180-102 = 78

63

The third angle is 34.5 degrees

The angles are 90 degrees, 57 degrees and the third angle is 33 degrees

63 degrees because 180 -39 -78 = 63

In degrees, its measure is 180 less the sum of the two angles at the base of the triangle.

If you mean an equilateral triangle then the 3rd angle is 60 degrees

If it is a triangle then the 3rd angle is 70 degrees
