1. In the image below, triangle DBA - triangle ECA. What is the distance across the lake?
56 m
20 m
15 m
45 m

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]
290d = 13050
d = 45
