The length of the lake as represented in the triangle ABC is 271.3 meters.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Sine rule is used to show the relationship between the sides and angles of a triangle.

∠A + ∠B + ∠C = 180° (angles in a triangle)

60 + 43 + ∠C = 180

∠C = 77°

Using sine rule:

519/sin(77) = BC / sin(60)

BC = 461.3 m

x = 461.3 - 190 = 271.3

The length of the lake as represented in the triangle ABC is 271.3 meters.
