10.9cm

Answer 2

Answer:

Length of BD.

Step-by-step explanation:

We know the value of angle CBD, and we know that for an angle x in a right triangle with hypotenuse h, non-hypotenuse side a adjacent to angle x, and side o opposite angle x, tan(x) = o/a. So:

tan(CBD) = height/BD

height = BD*tan(CBD)
