Answer:
<em>Angle C is equal to 30.</em>
Step-by-step explanation:
To find angle C, we have to find all the other angles first. They tells us the B ~= BAD ~= ADC. So, if we find ADC, we've found B and BAD as well. ADC is just 180 - 70 (the angle of ADE), which is 110. So, ADC, BAD, and B are equal to 110.
Remember, angles in a quadrilateral add up to 360. So, add all of the values of angles be have now and subtract from 360:
360 - (110 + 110 + 110)
360 - 330 = 30
Angle C should be equal to 30.

Answer:
1134
Step-by-step explanation:
Formula for diameter=2 x r
(π is 3.14)
Formula for area= π x r^2
So all you basically have to do is go backwords with the first one then plug the radius into the second one normally
38/2=19
Now just plug it into your second equation
π x 19^2=1134.11494795
And lastly round that to 1134, easy! :)
Three and six tenths
Hope I helped!
