Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.
The three angles of a triangle add to 180 degrees. If two of them add to 140 degrees then the third must be 180 - 140 = 40 degrees.
It must be 40 degrees. Because, the sum of internal angles should be 180 degrees. Accordingly, the third angle (C) = 180-(A+B) = 180 - (80+60) = 40 degrees
A scalene triangle
3 and it will be an equilateral triangle
40 degrees
since it is a right triangle there is one 90 degree angle and another of the angles is 45 degrees. there is 180 degrees in a triangle so the missing angle is 45 degrees.
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.

There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
An acute angled scalene triangle.
When each triangle has another angle that has the same number of degrees in each triangle, in addition to the specified angle of 44 degrees.
