  3.  θ = 72°

  4.  C = 108

Step-by-step explanation:

3. Solve for θ.

  θ = 360°(s/C) = 360°(24/120) = 72°

__

4. Solve for C.

  C = 360°(s/θ) = 360°(12/40°) = 108

The inside angles of a pentagon add up to 540 degrees. The four given angles add up to 433 which means that the interior angle that remains unknown is 107 degrees. That means that the measure of angle a is 73
