107 because the overall sum of exterior angles add up to 360

draw a triangle & its exterior angle on one side and name he exterior angle as4 and interior opp. angle as 1 and 2 and name the third angle as 3 now we know exterior angle is equal to the sum of interior opp. angle so,angle1+angle2=angle 4 we also know angle3+angle4=180(linear pair) NOW from this 2 equation angle1+angle2+angle3=180

Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150

The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.

The supplementary angle of the triangle.

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

A triangle has at two acute angles and the third angle is either an acute angle, a right angle or an obtuse angle.

As the sum of angles is a triangle is 180°, the third angle is 180-48-19=103°

The third angle of an isosceles triangle doesn't have a name.

The third angle is 30 degrees and it is an isosceles triangle.

The third angle is (128 degrees) minus (the second angle).

Two angles of a triangle add up to 65°. What is the measure of the third angle?

If two angles of a triangle each measure 55 what is the measure of the third angle?

The third angle must be 60 degrees so it is a scalene triangle

The third angle is 90 degrees so it is right angle triangle.

The third angle is 68 degrees which makes it a scalene triangle

The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson

The other acute angle in that triangle is 40 degrees.

The third angle measures 18 degrees.

If that's a triangle, the third angle is 90 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.
