A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
A 140 degree angle would be called an obtuse angle.
140 degrees
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.
The internal angles of a triangle add up to 180 degrees. 80 + 60 = 140 140 + x = 180 (x= the unknown angle) x = 180-140 x = 40 The unknown angle is 40 degrees
Sure. The other two angles would then be 20 each.
In a right triangle the greatest angle is 90 degrees.
Obtuse Triangle
If you mean the equal angles were each 70o then 180 - 140 ie 40o
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
A 140 degree angle would be called an obtuse angle.
60
The sum of the angles is 180 degrees in any triangle. So 180-140 is 40 and the third angle is 40 degrees.
140 degrees
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.
The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees
40 degrees ( 180 - 140 = 40 )
