Answer:
Step-by-step explanation:
In order to find r we have to square both sides of the equation
The *square root* sign cancels out the *squared* sign therefore:
to know if a polygon will tessellate one of the interior angles should be a factor of 360.
each angle of regular polygon = d = (n-2)*180
Answer:
1. -10
2. -11
Step-by-step explanation:
Answer:
a = 30
2a = 60
3a = 90
Step-by-step explanation:
3a + 2a + a = 180 ( Sum of angles of a triangle is 180)
6a = 180
a = 180/6
a = 30
2a = 2 x 30 =60
3a = 3 x 30 = 90
Answer:
That would be B Collinear
