Question

Two angles in a triangle add up to 98 degrees. what is the size of the third angle?

Answer 1

All 3 angles of a triangle add up to 180 degrees.

180 - 98 = 82

So 82 degrees is the third angle.

Answer 2

the answer is 82 the sum of all the angles is 180 and two of them add up to 98 so subtract 180-98=82 and the other angles measure 49 each
