Answer:

$x = 15 \: \: .....(5(15)- 14) = 61$

$(9x + 16 )= (5x - 14) + 90 \\ 9x - 5x = 90 - 14 - 16 \\ 4x = 60 \\ x = \frac{60}{4} \\ x = 15$

What is the length of CD? In this diagram, <br> ABC ~ EDC.

Alex777 [14]

Hey there!

Answer:

CD = 3.

Step-by-step explanation:

Since the triangles are similar, we can set up a ratio to determine the other side-lengths:

$\frac{12-x}{18} =\frac{x}{6}$

Cross multiply:

$6(12-x) = 18x$

Distribute the '6':

$72-6x = 18x$

Combine like terms and simplify:

$72 = 24x$

$x = 3$

Therefore, the length of CD is 3.
