Ответ:
This question is based on line segment. Therefore, the value of DA is 6.
Given:
DB= 9 and DC= 4
We need to determined the length of DA.
According to question,
In given figure, we observe that both the triangles are similar.Therefore we make proportion as below,
Substitute the given value in above proportion.We get,
Now, solve it further,
Thus, the value of DA is 6.

Ответ:
DA = 6
Explanation:
The triangles are similar, allowing us to make the proportion below
DB/DA = DA/DC
Plug in the given values. Cross multiply and solve for x
DB/DA = DA/DC
9/DA = DA/4
9*4 = (DA)*(DA)
36 = (DA)^2
(DA)^2 = 36
DA = sqrt(36)
DA = 6
The length of DA is exactly the geometric mean of the lengths BD and DC
geometric mean of x and y = sqrt(x*y)
