If sin A=1/2 find the cos A

1/2

Step-by-step explanation:

The sin of an angle = opposite side/hypotenuse.

1/2 shows us the ratio between side and hypotenuse is 1/2.

*If the hypotenuse is 2 and the opposite side is 1. The Pythagorean theorem states that: side 1^2 + side 2^2 = hypotenuse.

1^2 +1^2 = 2.

This shows us the adjacent side is 1.

Cos = adjacent/hypotenuse.

Cos = 1/2.

*(It could be more, but because it is a ratio 1/2 = 500/1000, so it still applies)
