Answer:

30 degrees

Step-by-step explanation:

The sum of exterior angles = 360 degree

102 + 73 + 67 + 88 + a = 360

330 + a = 360

a = 360 - 330

a = 30 degree.

Answer:

a = 30

Step-by-step explanation:

The total exterior angles of a pentagon is 360 degrees, meaning:

102 + 73 + 67 + 88 + a = 360

330 + a = 360

Subtract 330 from both sides:

330 + a - 330 = 360 - 330

a = 30

Hope this helps!
