40 degrees ! The internal angles of any triangle always total 180 degrees. Since you already know two angles (50 & 90) - the difference is 40.

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.
The other acute angle in that triangle 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?
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
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.
Third angle would be 46 degree. 180-44-90 =46
There are a total of 180º in a triangle.We know that one is 90º, because it's a Right Triangle, and another is 10º.Therefore, the third must be:180º - 90º -10º = 80ºt
A triangle has 180 degrees.A right triangle has exactly one angle measuring 90 degrees.If you know that one of the other angles of the triangle is 20 then your third angle is:180-90-20 = 70 degrees.
