A) find the length of each radius (radius of circle m and radius of circle n).

b) what does "point of tangency" mean? and identify the point of tangency.

c) write the equation of the tangent line at this point.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
