In degrees, its measure is 180 less the sum of the two angles at the base of the triangle.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
55°
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.
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
To find the measure of the third angle of a triangle, you can use the fact that the sum of all three angles in a triangle is always 180 degrees. So, if one angle measures 50 degrees and the other measures 85 degrees, you can subtract their sum from 180 to find the measure of the third angle. Therefore, the third angle would measure 180 - 50 - 85 = 45 degrees.
77. The sum of the three angles in a triangle equal the sum of 180 degrees
The third angle measures 18 degrees.
