 There are three figures.  Each figure has a circle and a triangle inside it.

The question asked is: How large is angle C.  To answer this question, you are given four choices and you have to select one choice which is correct.

Her the choice A is correct because any triangle has three angles and the sum of these angles is 180 .

So the angle C = 180 -angle A- angle B. this can be written as angle C = 180 - (angle A+ angle B)

Answer :  A.      angle C = 180 - (angle A + angle B)
