Answer 1

Explanation:

The answer I provide will only work for a 4 sided figure.

All 4 sided figures have interior angles that add to 360. You can use (sides - 2)*180 to get 360.

So what you have is 83 + 105 + 37 + x = 360 Combine the left.

225 + x = 360 Subtract 225 from both sides.

225-225+x = 360-225 Combine

x = 135

None of the answers work. You need a diagram or another fact.
