If the sin 30 degrees is 1/2 then the cos =

We have that if the sin 30 degrees is 1/2 then the cos __60=1/2.__

Option C

Question Parameters:

The sin 30 degrees is 1/2

Generally, the Trigonometry of a right angle triangle gives values for sin, cos, tan.

Using the triangle we have that

if the sin 30 degrees is 1/2 then the cos60=1/2

Therefore, if the sin 30 degrees is 1/2 then the cos __60=1/2__.
