107 rounded to the nearest 10th is 110
Answer: Choice A) 66 degrees
========================================================
Minor arc AB (marked in red in the attached diagram) is 45 degrees
Minor arc BE (marked in blue in the same diagram) is 87 degrees
Add the two arcs: 45+87 = 132
Then cut this value in half to get the inscribed angle ADE
132/2 = 66
We cut it in half due to the inscribed angle theorem
Notice how angle ADE cuts off arc ABE (which is composed of minor arc AB and and minor arc BE)
0=5-5x^2 you need first to find the complete square
(X-5/2)^2+4/25 so your vertex is (5/2,25) which is the curve of your graph,
