Answer 2

explain yourself

Explanation:

explain yourself, rather than writing the answer as x=88 explain why it is, for example we can say that

"since a four sided shapes total interior angles are 360⁰ we can add up the angles that we know, here 156, 69 and 47, giving us 272, subtracting that from 360 gives us 88 which is the answer for x"
