Answer:
[tex] \angle B= 39.81\degree[/tex]
Step-by-step explanation:
[tex] \because \tan \angle B = \frac {AC}{BC} \\\\
\therefore \tan \angle B = \frac {5}{6} \\\\
\therefore \tan \angle B = 0.833333333\\
\therefore\angle B= \tan^{-1}(0.833333333)\\
\therefore\angle B= 39.805569965\degree \\
\huge \purple {\boxed {\therefore\angle B= 39.81\degree}} [/tex]
