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)

Answer:
13 hours
Step-by-step explanation:
Let's first start by finding how much he makes in 1 hours:
Now we can set up two ratios
Solve by cross multiplying (multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction)
16x=208
Divide both sides by 16 to isolate x
x=13
He would have to work 13 hours to make $208
