Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula
. Remember that
is the center and
is the radius squared.
So, the equation of the circle must be
. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:

The end result matches with the equation determined before, so option A is the answer.

Answer:
140
Step-by-step explanation:
Angles in a triangle add up 180 :
180 = 107 + 33 + y
y = 180 - (107+33)
y = 180 - 140
y = 40
Angles on a straight line add up to 180 so :
180 = x + y
180 = x + 40
x= 180 - 40
x = 140
