this triangle, this side would be Bx, this side would be 1653.

It's an analogous search similar to this

triangle right here, so I can write that

1653.3 is related to the fourth

side as Bx is related to the sixth side.

And so I can solve for Bx directly. Bx ends up equaling

2480 pounds in tension, just like I found before.

So I can use that method of geometry as an alternative.

Now that I know Bx is equal to 2480. I know that

this 2480 and 1653 pounds must be balanced by TB2.

I can use Pythogoram's theorem to find out what the total magnitude is.

You can do that on your own and

then come on back. And oops,

what you should find is that

therefore TB2 equals the square

root of B sub x squared plus 1653.3

squared. I found B sub x to be 2480.

And so solving for TB2,

we get 2980 pounds in tension.
