A side of the triangle below has been extended to for an exterior angle of 161. Find the value of x
W. 19
E. 46
F. 134
Since the exterior angle formed has a measure of 161, the sum of the interior angles of the triangle at that vertex would be 180 - 161 = 19 degrees.
Since an interior angle and its corresponding exterior angle are supplementary, one of the interior angles adjacent to the exterior angle would be 180 - 19 = 161 degrees.
The other interior angle adjacent to the exterior angle would be the one opposite to the interior angle of 161 degrees. Thus, the value of x, which represents that angle, is 161 degrees.
Therefore, the answer is W. 19.
