pleaseeeee hlpppp. i just need the diagraam i can't figure it out.surveyor is measuring the length of a lake. He takes angle mea
surements from two positions, A and B that are 136 m apart and on the same side of the lake. From B, the measure of the angle betweet the sight lines to the ends of the lake is 130 degrees and the measure of the angle between the sight lines to A and one end of the lake is 120°. From A, the measure of the angle between the sight lines to the ends of the lake is 65 degrees, and the measure of the angle between the sight lines to B and the same end of the lake is 20 degrees Calculate the length of the lake, to the nearest metre. 20°..

Answer:
292 inches^2
Step-by-step explanation:
So to start off this is a picture of the fish tank.
Next we will find the area of the bottom and top rectangles.
The side lenghts for those two is 7 and 8.
So the area of one is 56 and the area of 2 is 112 inches^2.
Now we will find the area of the left and right rectangles.
The side lenghts are 6 and 8.
So the area of 2 is 96 inches^2.
Now for the front and back rectangles.
The side lenghts for those two are 6 and 7.
So the area of both is 84 inches^2.
So after adding all the areas up the surface area is 292 inches^2.
Here is the equation:
You need to find f(3). To do that, substitute all the x's with 3:
The first thing you need to do is multiply 4 by 3. Multiply:
Here is your new equation:
To get your answer, you need to add 12 and 1. Add:
That means:
