Answer:
Step-by-step explanation:
According to the ratios table, if
sin theta = 1/2
Then theta = 30°
Cos theta = cos 30° =root 3 /2
Step-by-step explanation:
[tex] \because \sin \theta = \frac{1}{2} \\ \therefore \sin \theta = \sin 30\degree \\ \\ \huge \red{ \boxed{ \therefore \theta = 30\degree }} \\ \\ \cos \theta = \cos 30\degree \\ \huge \purple{ \boxed{\therefore \cos \theta = \frac{ \sqrt{3} }{2} }} \\ [/tex]
