Answer:
Explanation:
Given that cos(60°) = 1/2, we can use trigonometric identities to find the sine, cosine, and tangent of 30°:
Sine of 30°:
sin(30°) = √[1 - cos^2(30°)] = √[1 - (cos(60°)/2)^2] = √[1 - 1/4] = √3/2.
Cosine of 30°:
cos(30°) = √[1 - sin^2(30°)] = √[1 - (√3/2)^2] = √[1 - 3/4] = √1/4.
Tangent of 30°:
tan(30°) = sin(30°) / cos(30°) = (√3/2) / (√1/4) = √3.
So, the sine of 30° is √3/2, the cosine of 30° is √1/4, and the tangent of 30° is √3.
