Answer:
the answer is 110
Step-by-step explanation:
In a regular pentagon the angles are 112. Take that number and replace x with 112
112-5= 107
112+30= 142
112-35= 77
Take those three numbers and subtract them from the sum 540 provided as a total of all five angles.
540-107-142-77-130-75= 9
You have 3 missing angles.
Nine divided by three is three.
Add three to each of the numbers you got for the missing angles.
107+3=110
142+3=145
77+3=80
Those are your missing angles.
I'm sure there is an shorter way of explaining it but this is how I did it and I got a 100 on the test.
