The compliment of a 100 degree angle is a 80 degree angle.
The sum of the angles in a trapezoid is 360 degrees, therefore, the forth angle in this problem is: 360 - (60+120+80) = 100 degrees
It is 80 degrees because supplementary angle add up to 180 degrees.
100.
An obtuse angled isosceles triangle.
The compliment of a 100 degree angle is a 80 degree angle.
If a triangle has a 100 degree angle, it is an obtuse triangle because a 100 degree angle is an obtuse angle. angle > 90 = obtuse angle = 90 = right angle < 90 = acute
180-100=80 degree angle
The supplement of an 80 degree angle is an 100 degree angle.
If you mean 100% grade, the answer is a 45 degree angle.
100
Angles can be complementary. A 100 degree angle is a complementary angle to an 80 degree angle in geometry studies.
A 100 degree angle is NOT an acute angle, it's an obtuseangle.Acute angles are less than 90 degrees, Obtuse angles are greater than 90 degress.
100
A 100 degree angle is obtuse
100/2 = 50; 50/2 = 25o
A trapazoid has those angles
