From the attachment, we have:
Required
Solve d
First, we need to calculate <C
--- angles in a triangle
Make <C the subject
Next, we apply Sine's law to solve for d
In this case:
Make d the subject
<em>Hence, the base of the lake is approximately 340.7m</em>
-3x-2-6x=-4-<em>(-4x)</em>+12
-9x-2=-16x+12
7x=14
x=2.
