If two tangent segments to a circle share a
common endpoint outside a circle, then the two segments are congruent. This
is according to the intersection of two tangent theorem. The theorem states
that given a circle, if X is any point
within outside the circle and if Y and Z are points such that XY and XZ are
tangents to the circle, then XY is equal to XZ.

<u><em>Answer: </em></u>
<u><em>x
= -3 + Y/2 </em></u>
<u><em>y= 6 + 2x </em></u>
<u><em>Hope this helps!:3 </em></u>
Y = 5 - 4x 5 - 4x = x^2 - 2x - 19 0 = x^2 + 2x -24 0 = (x + 6)(x - 4) Therefore x = -6 (Given) or 4 x = 4, y = -9 (4,-9) is the other solution
