A scalene triangle
There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
If you mean an equilateral triangle then the 3rd angle is 60 degrees
40 degrees
It is a scalene triangle as there are no equal angles or lengths. 60 + 70 + 50 = 180 degrees
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.

40 degrees
It is a scalene triangle as there are no equal angles or lengths. 60 + 70 + 50 = 180 degrees
40 degrees
180 - ( 80 + 60 ) = 40 the answer would be 40 degrees
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.
180 - (80 + 60) ie 40
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.
