Answer:

k = 2

Step-by-step explanation:

To get the variable k alone, you must add (-1) from the left side and add (1) to the right side.

k - 1 = 1

+1 +1

k = 2

Answer:-
k=2

Solution:
k-1 = 1
k = 1+1

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)
