All triangle angles add to 180 degrees. Since one is 38 and the right angle is 90, the third angle is 180 -38-90 = 52 degrees
The third angle is (128 degrees) minus (the second angle).
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

...a right triangle.
Remember in a right angles triangle, the right angle is 90 dgrees. The sum of the three angles in a triangle is 180 degrees. Hence x + 57 + 90 = 180 x + 147 = 180 Subtract 147 from boths sides x = 33 degrees.
The other acute angle in that triangle is 40 degrees.
If two angles of a triangle each measure 55 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.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
All triangle angles add to 180 degrees. Since one is 38 and the right angle is 90, the third angle is 180 -38-90 = 52 degrees

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.
Third angle would be 46 degree. 180-44-90 =46
