Best Answer

The three angles of a triangle add to 180 degrees. If two of them add to 140 degrees then the third must be 180 - 140 = 40 degrees.

A triangle has one angle of 80 degrees and another of 60 degreesHow many degrees must there be in the third angle?

Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.


A triangle has one angle of 80 degrees and another of 60 degreeshow many degrees must there be in third angle?

It must be 40 degrees. Because, the sum of internal angles should be 180 degrees. Accordingly, the third angle (C) = 180-(A+B) = 180 - (80+60) = 40 degrees

What is another measure for an angle that measured 283 degrees?

If your measuring it to the vertical antoher measure would be 13 degrees. If your mesauring it to the horizontal another measure would be 77 degrees. If you take this angle another 360 degrees a corresponding angle would be 643. If you take this angle another 360 degrees a corresponding angle would be 1003. You can keep doing this infinitely. Just add 360 and it will be the same angle since you are going in a circle.


What angle equals 140 degrees?

An angle that equals 140 degrees would be considered an "obtuse" angle. This is because it is greater than 90 degrees but does not exceed a straight line of 180 degrees.
