need these done by tomorrow - trig

i accidentally posted these in the trig help forum.

10) Give that tanhttp://i38.tinypic.com/es3m6t.png = -1/7 and sinhttp://i38.tinypic.com/es3m6t.png > 0, use the x-y-r method to find sinhttp://i38.tinypic.com/es3m6t.png and coshttp://i38.tinypic.com/es3m6t.png.

11) Sketch a 240° angle in standard position. Label a point on its terminal side, draw the right triangle in use, indicate the direction of opening, and give all six trig function values for 240°.

12) Sketch a 90° angle in standard position. Label a point on its terminal side and use the x-y-r method to compute the six trig function values for 90°.

13) In what quadrant(s) does http://i38.tinypic.com/es3m6t.png terminate if sinhttp://i38.tinypic.com/es3m6t.png > 0 and coshttp://i38.tinypic.com/es3m6t.png < 0?

17) Use a fundamental identity to find coshttp://i38.tinypic.com/es3m6t.png if sinhttp://i38.tinypic.com/es3m6t.png = 1/5, http://i38.tinypic.com/es3m6t.png that terminates in Q2. Show work.
