Question

Can anyone help me with these 8 answers pls ASAP

Answer 1

`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} (28)/(sin63)=(29)/(sinB) \\ \\ sinB=(29sin63)/(28) \\ \\ sinB=0.9228 \\ \\ B=67.34^o \end{gathered}`

Thus;

`m\angle B=67.34^o`
