Question

26. Julie says that sin A/cos A = tan A and sin B / cos B = tan B. Use the triangle shown to prove

Julie's statements true or false. Make sure you enter your work

-confused as to what this even means.

Answer 1

Julie is correct because:

`(\sin A)/(\tan A)=(a/c)/(b/c)=a/b=\tan A \\ \\ (\sin B)/(\cos B)=(b/c)/(a/c)=b/a =\tan B`
