A mountain climber, in the process of crossing between two cliffs by a rope, pauses to rest. she weighs 510 N. As the drawing shows, she is close to the left cliff than to the right cliff, with the results that the tensions in the left and right sides of the rope are not the same. Find the tensions in the rope a) to the left and b) to the right of the mountain climber.

(ignore the dots i'm trying to give a rough estimate of the picture)
the left top angle is 65 degrees
the right top angle is 80 degrees

I have been trying this question for a while now. and i guessed that -T1sin65 + T2sin80 = 0
+T1cos65 - T2cos80 = 0

and i further went on to finally get T1 = 2048.3 N
and T2 = 1885.2 N

but i know these are wrong. am I doing it partially corrected? How do I do this problem, its been since high school since I did it. Any help is appreciated. thanks.

We have to make some sort of structure in physics float. We can use whatever mold or anything inside it. It has to be concrete though. How do we do it?
