It is a triangle that has these 3 angles at its corners: 30, 60 and 90 degrees. This is one of the more common triangles as many designs are laid out at 30 degrees or 60 degrees.
Any angle you like, between 0 and 360 degrees (excluding the extreme values). The only constraint is that the sum of all the interior angles must be (19-2)*180 = 17*180 = 3060 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 180 x 17 = 3060 3060/19 = 161.05
It is: MMMLX = 3060
3060
3060
a right angle is a right angle
3060 divided 36 = 85
The LCM of 3060 and 135 is 9180
3060
Because a right angle is a right angle.
A right angle is an angle of 90 degrees.
The sum of the interior angles of a polygon can be calculated using the formula (n-2) * 180 degrees, where n is the number of sides. For a 19-sided polygon, the sum of the interior angles would be (19-2) * 180 = 17 * 180 = 3060 degrees.
