A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
Any angle between 90 and 180 degrees is an obtuse angle. Therefore: 160 degrees is an obtuse angle.
An angle that is 160 degrees would be an "obtuse" angle. This is because the measurement of degrees exceeds 90. Anything below 90 degrees would be an "acute" angle.
160
20 degrees
An obtuse angle is an angle between 90 degrees and 180 degrees. A 180 degree angle is a straight horizontal line. So you can imagine that a 160 degree angle is almost but not quite horizontal.
160
160 The 2 angles must equal 180 degrees, so 160 is the answer.
18
A regular octdecagon (18 sided geometric figure) was internal angles of 160 degrees.
An obtuse angle because it's greater than 90 but less than 180 degrees
A pair of supplementary angles add up to 180 degrees. Therefore, the supplement to a 20 degree angle is equal to 180 - 20 = 160 degrees.
An angle of 160 degrees is an obtuse angle
No, 160 degrees is an obtuse angle.
180 - angle = supplement 180- 160 = 20 degrees
An obtuse angle
An obtuse angle.
