Using the concept of similar triangles, the depth of water, d from the shore is 15 feets
From the figure attached ; the following relationship can be established :
- [tex]\frac{5}{1.5} = \frac{50}{d}[/tex]
Using cross multiplication :
[tex] d \times 5 = 50 \times 1.5 [/tex]
[tex] 5d = 75 [/tex]
Divide both sides by 5
[tex]\frac{5d}{5} = \frac{75}{5} [/tex]
[tex] d = 15 [/tex]
Hence, the depth of water from the shore ls 15 feets.
