You should add the picture, but maybe a hexagon?
Answer:
The answer is D: 130
Step-by-step explanation:
(3x-28) +90+(66-x) = 180
2x + 128 = 180
2x = 52
x = 26
Therefore Angle AOE = 90 + (66-26)
= 130
The percent error is 4.167 %
<em><u>Solution:</u></em>
Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour
When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour
<em><u>The percent error is given by formula:</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

From given,
Experimental value = 50
Theoretical value = 48
<em><u>Substituting the values in formula, we get,</u></em>

Thus the percent error is 4.167 %
