The angles in a triangle add up to 180, so the answer is b. 40 degrees.

In a triangle, all angles added together must equal 180 degrees. Subtract the existing angles from 180 to get your 3rd angle:
180-80-60=40
Your 3rd angle will be 40 degrees.

The sum of the interior angles of any triangle is 180 degrees. Just subtract the 2 angles you already have from 180 and you are left with 40 degrees for the third angle.

If this is a right angled triangle it must add up to 90 degrees, so the correct answer is a) 30 degrees as this is 90degrees minus 60 degrees.
How could the other people answering this be so stupid to get such a simple sum wrong. Fortunately, you won't be so stupid when you give the teacher your answer.

The angles in a triangle must add up to 180 degrees.
80 + 60 = 140
180 - 140 = 40
So choice B!

40, 80+60=140
180-140=40

You need to know that the sum in a triangle is always 180 degrees.

seriously?!
40 degrees, but that's hardly difficult

one hundred eighty-one hundred forty=40 (a million triangle=one hundred eighty) I constantly remembered that a triangle further up one hundred eighty by technique of thinking of a sq., in case you decrease a sq. diagonally you get 2 triangles (A sq.=360) so in case you divide that by technique of two you have one hundred eighty levels.
