Step-by-step explanation:
Got this from another Brainly user
Given CD is an altitude such that AD=BC , AB=3 cm and CD= √2 cm.
Let AD=x, Since given AB=3
AD+DB=3
x+DB = 3
DB = 3-x
Since ΔBCD is rght angle triangle, let's apply Pythagoras theorem



Since given AD=BC,let us plugin BC=x in above step.


6x=11
x=
Now we know AD=x=
and given CD=√2.
Let us apply Pythagoras theorem for ΔACD



= 2.315cm
Thank you for posting your question here at brainly. The answer to the above question is the first one in the choices which is 15. Below is the solution:
<span>
3x + 10 = 55
Subtract 10 from each side...
3x = 45
Divide by 3...
x = 15</span>
