Answer: x = -2

Step-by-step explanation:

4/2 = 2

3x - 8 = 8x + 2

Subtract 2 from each side

3x - 10 = 8x

Subtract 3x from each side

-10 = 5x

Divide each side by 5

-2 = x

Consider the diagram below where CD and BC are tangent to circle A. CD = 18 cm and CE = 8 cm. What is the length of the radius o
Ksivusya [100]

Answer:

The length of the radius of circle is 16.25 cm

Step-by-step explanation:

we know that

If CD is tangent to circle A at point D

then

the segment CD is perpendicular to the radius AD

and

ACD is a right triangle

so

Applying the Pythagorean Theorem

AC^2=AD^2+CD^2

we have

AC=AE+CE=(r+8)\ cm\\AD=r\ cm\\CD=18\ cm

substitute

(r+8)^2=r^2+18^2

solve for r

r^2+16r+64=r^2+324\\16r=324-64\\16r=260\\r=16.25\ cm
