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!
