Answer:

d = 45

Step-by-step explanation:

It is stated that ECA and DBA are similar triangles.

To find the distance across the lake we can use the similarity ratio:

CE/BD = CA/BA

[tex] \frac{d}{30} = \frac{435}{290} [/tex]

Cross multiply fractions

290d = 13050

Divide both sides by 290

d = 45
