Section 6.2

Can you do 49 for me?

Sorry but I can't read your reply.

Do what I do:

1. Solve on paper.
2. Take a picture with your phone.
3. Click on "Upload a File"
4. Post your thread.

You can also post using math notation from Wolfram like you sometimes do. Now, the PM about the lease.

θ= 6° -> angle with the horizontal
φ=90+θ=90+6=96°-> angle between the horizontal and left wire
φ=90-θ=90-6=84°-> angle between the horizontal and right wire

left wire:
L^2=100^2+75^2-2*100*75*cos(96)
L^2=17192.926949014804
L=sqrt(17192.926949014804)
L=131.12ft

right wire:

R^2=100^2+75^2-2*100*75*cos(84)
R^2=14057.073050985198
R=sqrt(14057.073050985198)
R=118.56ft

Much better. Thank you so much. You're the best.
