Solve for a.

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
