@brianjr227  what is sin50 degree(use formula)?

mayankdevnani · Answer

$$\huge \bf \sin=\frac{perpendicular}{hypotenuse}$$

mayankdevnani · Answer

so $$\huge \bf what~is~\sin50^{\circ}??$$

mayankdevnani · Answer

@brianjr227   can you find out?

anonymous · Answer

how you solve sin50 though?

anonymous · Answer

is it A? or is that wrong

mayankdevnani · Answer

because $$\huge \sin50^\circ=\frac{base}{7}$$
that's why we use sin50

mayankdevnani · Answer

yeah. its A

mayankdevnani · Answer

becuase opposite of sin is cosec.
$$\huge \bf \sin=\frac{1}{cosec}$$

mayankdevnani · Answer

understood?  @brianjr227
