Determine if the statement is always, sometimes or never true. the measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle. always sometimes never

Step-by-step explanation:

The exterior angle is supplementary to the adjacent interior angle. If that interior angle is 90°, then the interior and exterior angles are equal in measure.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
