The sum of all exterior angles add up to 360º. To find the missing 3rd exterior angle subtract the sum of the first two exterior angles from the total sum of all exterior angles.
360º - 220º = 140º
The measure of the third exterior angle is 140º.
Answer:
the cost or price of something
Step-by-step explanation:
10-2/3=9 1/3 if you estimate that it would be 9
next it is 3 - 1/8= 2 7/8 estimate it would be 3
so 9 x 3= 27
24+3.1+(-44)+(-8.2)+63= 24 + 3.1 - 44 - 8.2 + 63= 87 + 3.1 - 44 - 8.2= 43 + 3.1 - 8.2= 43 + 3.1 - 3.1 - 5.1= 43 - 5.1= 43 - 3 - 2.1= 40 - 2.1<span>= 37.9</span>
