Right triangle ABCABC has its right angle at C.
AC=12AC=12 and BC=5BC=5 .
Which trigonometric ratios are correct?
Select each correct answer.
cosA=1213cosA=1213
sinB=1213sinB=1213
tanB=512tanB=512
sinA=513sinA=513
tanA=1213
+1252 
\(cosA=12/13\) so that is right.
\(sinB = 12/13\) so that is right.
\(tanB = 12/5\) so that is not right.
\(sinA=5/13\) so that is right.
\(tanA = 5/12\) so that is not right.
You are very welcome!
