Question

ROUND YOUR ANSWER TO THE NEAREST TENTH.a) 38.2b) 53.8c) 37.9d) 55.1

Answer 1

we use the sinus law,

`\begin{gathered} (a)/(\sin A)=(c)/(\sin C) \\ (26)/(\sin 88)=(21)/(\sin C) \\ \sin C*(26)/(\sin 88)=21 \\ \sin C=21*(\sin 88)/(26) \\ \sin C=0.807 \\ C=\sin ^(-1)(0.807) \\ C=53.8 \end{gathered}`

answer:

b) m
