Question

If sinA =root3/2,then write the value of A

Answer 1

$\sin(a) = \frac{ \sqrt{3} }{2}$
we know the sin a value . By the trigonometric ratio chart .
sin60 has that value.
$\sin(60) = \frac{ \sqrt{3} }{2}$
There fore a is equal to 60.

Answer 2

sinA=root 3 /2
since root 3/2is equal to si 60
so sinA=sin60
and A=60
