Answer:


y=3√(7)\ units

Explanation:

see the attached figure with letters to better understand the problem

we know that

In the right triangle ABD


tan(<BAD)=y/9

In the right triangle BCD


tan(<CBD)=7/y

remember that

m< BAD=m<CBD

therefore


tan(<BAD)=tan(<CBD)

equate the equations


y/9=7/y


y^(2)=63


y=3√(7)\ units
