Answer 1

Answer:

$sin \: 2A = 0 \\ sin \: 2A =sin \: 0° \\ \blue{\mathfrak{\underline{\large{On \: comparing}}}:} \\ 2A = 0 \\ \boxed{A = 0} \\ Therefore, \\ cos \: A = cos \: 0 =⟩ 1 \\ \rightarrow \: (c) \: is \: the \: correct \: answer \\ \\\red{\mathfrak{\underline{\large{Hope \: It \: Helps \: You }}}} \\ \green{\mathfrak{\underline{\large{Mark \: Me \: Brainliest}}}}$
