Which of the following steps is needed to circumscribe a circle about
A. Construct one perpendicular bisector of the triangle
B. Construct one angle bisector of the triangle
C. Construct two perpendicular bisectors of the triangle
D. Construct two angle bisectors of the triangle

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

stethere all not eveanp-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
