Look up "sum of interior angles of a polygon" on Google.  There you will find a formula for predicting the number of interior angles that a given polygone will have.  This formula is <span> (n - 2) × 180°, where n represents the number of sides of the polygon in question.  Count these sides.  Substitute your value for n into this formula.  The interior angles of your polygon add up to the result of evaluating this formula.  Call this "sum."  Then:

"sum" = (the one unknown interior angle) + (the sum of the given (known)) interior angles).</span>

Answer:

The second choice.

Step-by-step explanation:

The length of AC must be equal to 5, since it is horizontally five units. We can rule out the first option.

Length BC cannot be the square root of 16, since that would be exactly 4 units. BC is slanted and does not represent a completely vertical line, so it is not a whole number. We can rule out the fourth option.

Length AB cannot be a whole number, being a slanted line that crosses a total of more than four units. Option three can be ruled out.

Therefore, we are left with the second option.
