Exterior angle of any plane figure total 360 degrees, so 360 - (110 + 100) ie 360 - 210 = 150
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
120 degrees.
20 degrees
105
77 degrees
105 degrees
In any triangle exterior angle plus interior angles = 180 degrees
80 degrees.
100 degrees
They are all 60 degrees.
An exterior angle of a triangle can have a value between (but not including) 0 to 180 degrees.
120 degrees.
The 3rd angle of the triangle could be 90 degrees because the 3 angles in a triangle add up to 180 degrees.
Consider a right triangle. One of the exterior angles 90 degrees.
It is a right angle triangle and the 3rd angle will measure 30 degrees
They each measure 60 degrees
150 degrees
