If you are solving for x in the diagram shown, which fact would you to set up the problem? a) tangents touch a circle in exactly one point. b) chords that intercept congruent arcs are congruent to each other. c) tangent segments from the same point outside the circle are congruent. d) the product of the segments formed by intersecting chords are congruent.

Tangent segments from the same point outside the circle are congruent. This Geometric Theorem allows you to set up the problem and solve for x.

Step-by-step explanation:

Tangent segments from the same point outside the circle are congruent. (c) i got it right on USATESTPREP

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
