Question

find the value of a 2 sin a =1 find the value of a

Answer 1

sin a=1/2
we know that sin 45°=1/2
so a=45°

Answer 2

$\huge \tt 2 \:sin \: a \: = 1$

$\huge \tt sin \: a \: = \frac{1}{2}$

$\huge \tt as \: \: we \: \: know \: \: \: that \: \: \:$

$\huge \tt sin \: 30 \degree = \frac{1}{2} \: \: \: then$

$\huge \tt sin \: \: a \: \: = \: \: sin \: \: 30 \degree$

$\huge \tt then ,$

$\huge \boxed{ \boxed{ \pink{\tt a = 30 \degree}}}$
