Can anyone help me with these 8 answers pls ASAP

Answer 1

SOLUTION:

$m\angle C=63^o,AB=28,AC=29,find\text{ }m\angle B$

A simple sketch will help;

We can use the sine rule to solve for the angle B;

$\begin{gathered} \frac{28}{sin63}=\frac{29}{sinB} \\ \\ sinB=\frac{29sin63}{28} \\ \\ sinB=0.9228 \\ \\ B=67.34^o \end{gathered}$

Thus;

$m\angle B=67.34^o$
