Answer:
y = √(55).
Step-by-step explanation:
Triangles ADC and DBC are similar, so we have
(6+5) / y = y / 5
11/y = y/5
y^2 = 55
y = √(55).

------------------------
Steps:
1st write out equation
Second write the conjugant and multiply it.
![\frac{\sqrt{60}}{\sqrt{5}} * \frac{\sqrt{5} }{\sqrt{5} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B60%7D%7D%7B%5Csqrt%7B5%7D%7D%20%2A%20%5Cfrac%7B%5Csqrt%7B5%7D%20%7D%7B%5Csqrt%7B5%7D%20%7D)
After multiplying you should get,
![\frac{10\sqrt{3}}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5Csqrt%7B3%7D%7D%7B5%7D)
now after simplifying you should get
