Answer 1

Answer : A

The total degrees of a triangle is 180, a triangle has 3 angles

If two angles measure to be 120, than you have to do 180-120, to find out the degree of the third angle.

180-120 = 60

we know that the third angle must be 60, so A is your answer.

Answer 2

The answer is A

Because the sum of a triangle is equal to 180°,
So 60+60+60 = 120+60 =180
