Let's say that the angles of this triangle is supplementary. So our equation will be: 80 + 60 + x = 180 Solve for x (80 + 60) 140 + x = 180 x = 180 - 140 x = 40 That is the measurement of the third angle. To check, just simply add the 3 and you'll get 180 - ericka janolo http://www.friednster.com/ekang03
The third angle is 90 degrees so it is right angle triangle.
The third angle has to be 90 degrees so it would be a right angle triangle.
isoselles triangleImproved Answer:-The third angle has to be 90 degrees so it is a right angle triangle.
The third angle is (128 degrees) minus (the second angle).
The third angle is 34.5 degrees
If that's a triangle, the third angle is 90 degrees.
30 degrees
The third angle is 90 degrees so it is right angle triangle.
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
The third angle has to be 90 degrees so it would be a right angle triangle.
The third angle must be 30 degrees so it is an obtuse triangle

The third angle is 34.5 degrees
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
If you mean an equilateral triangle then the 3rd angle is 60 degrees
A right angle triangle and the third angle measures 60 degrees
