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
