Step-by-step explanation:

well, the principle here is that the sum of all angles in a quadrilateral shape is 360°.

so, all 4 angles together must be 360.

and the missing angle C is then

360 - 113 - 113 - 88

and the only expression in the list of answer options that does the same thing is C

360 - (113 + 113 + 88)
