Question

In the diagram below, BC is an altitude of ABD. To the nearest whole unit, what is the length of CD?

Answer 1

do you know the altitude theorem inside a right triangle from the right angle on hypothenuse ?

Answer 2

We can solve this by using geometry and trig.

Answer 3

I think this property can help
H^2=m*n
Where h is altitude m is what u want and n is 44

Answer 4

BC^2 = DC*CA
from what you can calculi the length of DC easy

Answer 5

i got 23.27 - what rule/property is that formula? @jhonyy9

Answer 6

what have wrote above @isaidavila - ok. ?
