The correct answer is 3



the triangle sides are equal. so :
4x - 1 = 2x + 5 \\ 4x - 2x = 1 + 5 \\ 2x = 6 \\ x =  \frac{6}{2}  = 3

The equation of a circle is (x - 3)^2 + (y + 2)^2 = 25. The point (8, -2) is on the circle.
Jlenok [28]
From the equation, you can see that (3,-2) is the center of the circle (the terms are 0 for those x,y values). The mentioned point has the same y value as the center. That's good news, because it tells us that the tangent line is exactly vertical. The x coordinate is given as x=8. Vertical lines have an equation of x=... so x=8 is the right answer.
