Answer 2

Answer:

$\red { \angle A}\green {= 60\degree }$

$\red { \angle C}\blue {= 30\degree }$

Step-by-step explanation:

$Given \: In \: Right \: triangle \: ABC , \angle = 90\degree$

$AB = 3\:cm , \: AC = 6\:cm$

$i) sin \angle C = \frac{AB}{AC}\\= \frac{3}{6}=\frac{1}{2}$

$\implies sin\angle C = sin \:30\degree$

$\implies \angle C = 30\degree$

$ii) cos\angle A = \frac{AB}{AC}\\= \frac{3}{6}\\= \frac{1}{2}$

$\implies cos \angle A = cos \:60\degree$

$\implies \angle A = 60\degree$

Therefore.,

$\red { \angle A}\green {= 60\degree }$

$\red { \angle C}\blue {= 30\degree }$
