Answer:
COSB= 8/17
TANA=8/15
Step-by-step explanation:
[tex]for \: the \: cosine \: of \: angle \: b \\ we \: should \: note \: that \: cosb = \frac{adjacent}{hypothenus} \\ from \: the \: shape \: cosb = \frac{8}{17} \\ for \: the \: tangent \: of \: angle \: a \\ tan \: a = \frac{opposite}{adjacent} \\ tan \: a \: = \frac{8}{15} [/tex]
