Want this question answered?
the angle on a straight line is 180 degrees, the angle of semicircle at centre is 180 degrees
With the protracter, its 180 degrees!!
If one interior angle is 165 degrees, find the number of sides of the polygon.
180 minus interior angle = exterior angle because there are 180 degrees on a straight line
Supplementary angles are angles that add up to 180 degrees, ie. a straight angle. Therefore, the angle supplementary to 101 degrees would be 180-101=79 degrees.
Find any straight side of the decagon. Move along it until it joins another side. That is where an angle is. An angle of a decagon can have any measure between 0 and 360 degrees (except 180 degrees).
you find a straight angle across ur curtains
to find the the exterior angle, divide 360 degrees by the number of sides. so the answer is 15 degrees.
90 degrees
90
By dividing the number of its sides into 360 degrees
The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.
