$\sqrt{55}$

Step-by-step explanation:

∆ BCD ~ ∆ DCA

$\frac{bc}{dc} = \frac{dc}{ac}$

Plug the values:

$\frac{5}{y} = \frac{y}{6 + 5}$

$\frac{5}{y} = \frac{ y}{11}$

Apply cross product property

$y \times y = 11 \times 5$

Calculate the product

${y}^{2} = 55$

$y = \sqrt{55}$

Hope this helps...

Good luck on your assignment..

Step-by-step explanation:

3x =15-5y

Add 5y and subtract 3x on both sides

5y=15-3x

y=(15-3x)/5
