Determine the values of sinA, cosA, tanA, sinB, cosB, cotB, and angles A and B if a = 5 b = 12 and c=13
Just read the values straight off the triangle.
for example
SinA = opp/hyp = a/c = 5/13
etc
To remember the ratios it is
Some old hags
can't always hide
their old age
Which stand for:
sin=opp/hyp
cos=adj/hyp
tan=opp/adj
