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

What if two angles of a triangle are complemenatr 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.

What is the third angle measure of a right triangle if one of the angle measures 10 degrees?

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


If one angle of a right triangle measures 20 degrees the other angle must measure?

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.
