Answer:

$FC=25.9$

Step-by-step explanation:

<u>Congruent Triangles</u>

The figure shows two triangles FCD and FED. One of their sides is the radius of the circle, they both form a 90° angle with the line CD and ED and they share the same segment FD.

Thus, both triangles are congruent and we have the length of a side (12 units), one common side (the hypotenuse) and one unknown leg that must be equal. Therefore

$13x-16=4x+11$

Solving

$9x=27$

$x=3$

The required side FD is the hypotenuse of any of the triangles. The unknown leg can be calculated by

$13x-16=23$

$4x+11=23$

Thus

$FD^2=12^2+23^2=673$

Solving

$FD=\sqrt{673}$

$\boxed{FC=25.9}$

Find the x and y intercepts 8x-4y= -16

scZoUnD [109]

$8x-4y=-16\\\\x-intercept\ for\ y=0:\\\\8x-4(0)=-16\\\\8x-0=-16\\\\8x=-16\qquad\text{divide both sides by 8}\\\\\boxed{x=-2\to(-2,\ 0)}\\\\y-intercept\ for\ x=0:\\\\8(0)-4y=-16\\\\0-4y=-16\\\\-4y=-16\qquad\text{divide both sides by (-4)}\\\\\boxed{y=4\to(0,\ 4)}$
