The sum of exterior angles of a polygon = 360<span>°
Thus, the eighth exterior angle is equal to
360</span>° - (42° + 55° + 39° + 20° + 62° + 45° + 47°) = 50<span>°</span>
Answer:
75%
Step-by-step explanation:
The <em>number </em>increase is 9. 9 is what percent of 12? 9 is 75% of 12
(x + 12) = (x + 14) - 3
subtract 12 from each side
x = x + 14 - 3 - 12
Now if we subtract x from each side we see that x - x = 0. Combine the terms left over and we have -1, so
0 = -1
The answer is NO SOLUTION
