Question

Can someone please help me find the measure of the exterior angle.

Answer 1

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer 2

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°
