Question

if sin 2A=½ then angke A is: (a) 60° (b) 30° (c) 15° (d) 0°
​

Answer 1

Answer:

Please mark my answer as the brainliest, it would mean a lot

A=15°

Step-by-step explanation:

sin2A=1/2=sin30°

2A=30°

A=15°

Answer 2

$\sin \: 2A = \frac{1}{2} \\ then , \: \sin \: A \: = \frac{½}{2} \\ \sin \: A \: = \frac{1}{2} \times \frac{2}{1} \\ 2 \: and \: 2 \: will \: be \: cancelled \: : \\ So, \sin A= 1 \\ And, \: A = 90° \\ \\ your \: answer \: is \: 90° \\ but, it \: is \: not \: in \: the \: option.. \\ hey \: I \: don't \: know \: more \: \\ I'm \: sorry.. \\ have \: a \: nice \: day \\ borahae..♥$

may be @svijayan's answer is correct..
