given cos sigma = -12/13, sigma in quadrant III, how would you go about to find the remaining trig functions of sigma?

Question

anonymous · Answer

the right angled triangle with two sides of 12 and 13 is special its one which has 3 sides  of lengths which are whiole numbers 
hypotenuse = 13 and two legs are 5 and 12

anonymous · Answer

adj side= 12
hypt = 13
so oposite side = 5

this is the triangle formed by your angle

anonymous · Answer

ok and would the sigma be the 90 degree angle then?

anonymous · Answer

sine sigma = -5/13
tan sigma = -5 / -12 = 5/12
