Question

Find the missing side length for c and the missing angle measures for a and b in the image above

Answer 1

I really don't understand this one

Answer 2

\[c=\sqrt{1^2+\left(\sqrt{3}\right)^2}=2\]\[b=\text{ArcTan}\left[\frac{\sqrt{3}}{1}\right]=\frac{\pi }{3}=60{}^{\circ} \]\[a=90{}^{\circ}-60{}^{\circ}=30{}^{\circ} \]

Answer 3

thank you
