It is a right angle triangle and its 3rd angle is 70 degrees.
Each exterior angle measures 20 degrees Each interior angle measures 160 degrees
The 3rd angle is 70 degrees which would form a right angle triangle.
Its exterior angle is 20 degrees and it will have 360/20 = 18 sides
18 degrees
The angle of reflection is equal to the angle of incidence, so if the angle of incidence is 20 degrees, then the angle of reflection will also be 20 degrees.
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
100
The angle of reflection will be equal to the angle of incidence, which is 20 degrees in this case.
It is a right angle triangle and its 3rd angle is 70 degrees.
Between 15 and 20 degrees...
It is: 160 degrees
20 degrees
Exterior angle = 20 degrees Interior angle = 160 degrees
90 - 20 = 70 degrees.
Each exterior angle measures 20 degrees Each interior angle measures 160 degrees
The 3rd angle is 70 degrees which would form a right angle triangle.
