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.

-----o---------
(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.

Calculate the number of mg of Mn2+ left unprecipitated in 100 mL of a 0.1000 M solution of MnSO4 to which enough Na2S has been added to make the final sulfide ion (S2-) concentration equal to 0.0394 M. Assume no change in volume due to the addition of Na2S. The pKsp of MnS is 14.960

Mathhater/phobe, so pls be patient and use itty bitty words in the explanation, at abt a 2nd grade level if you can.

WHY on earth did my HS teachers (years ago) have such a fixation on doing things the hard way? IIRC, they were insistent that we bisect angles with JUST a straightedge and compass (goodness knows why!). Or see if triangles were identical or congruent or whatever the heck it was with some weird angle-side-angle or angle-angle-angle arguments (every triangle I EVER saw had 3 angles and 3 sides; what the ^%^#$*# were they talking about, anyway?).

It's been years, and I'm **still** wondering. What's the practical reason for doing things in such a bass-ackwards, round-about way, instead of just grabbing a protractor or other doodad and just MEASURING the darned thing?

I'm being utterly serious here. If it's **that** important to bisect or trisect an angle, why not use reasonably accurate ("within tolerances") and readily available tools to do it?

Help!
