The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
If you mean an equilateral triangle then the 3rd angle is 60 degrees
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.
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
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 has to be 90 degrees so it would be a right angle triangle.

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.
A right angle triangle and the third angle measures 60 degrees
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
Right angled triangle because the third angle must be 90 degrees.
The third angle must be 60 degrees so it is a scalene triangle
The third angle is 75 degrees. The 3 angles of a triangle add up to 180 degrees. Therefore: 45 + 60 + 75 = 180.
40 degrees
If it's a right angle triangle then the the third angle is 60 degrees.
