Possible measures of three angles of a triangle are
-
- 33°, 42°, 115°
- 40°, 70°, 80°
- 30°, 60°, 100°
- 50°, 60°, 70°
Correct Option: D
As we know that The sum of all the angles of a triangle is 180°.
From option (4) ,
50° + 60° + 70° = 180°
Hence , Possible measures of three angles of a triangle are 50°, 60° and 70° .
