The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
55°
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?
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.
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.
Also 45
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.
