What is the value for $$ \cos $$ $$ 30^{\circ} $$

Question

UpStudy AI · Accepted Answer

1. We start with the known trigonometric value:
   $$
   \cos 30^{\circ} = \frac{\sqrt{3}}{2}
   $$

2. This result comes from the properties of a $$30^{\circ}-60^{\circ}-90^{\circ}$$ right triangle, where:
   - The side opposite $$30^{\circ}$$ has length $$1$$,
   - The side opposite $$60^{\circ}$$ has length $$\sqrt{3}$$,
   - The hypotenuse (opposite $$90^{\circ}$$) has length $$2$$.

3. Using the definition of cosine in a right triangle:
   $$
   \cos 30^{\circ} = \frac{\text{Adjacent side to } 30^{\circ}}{\text{Hypotenuse}} = \frac{\sqrt{3}}{2}
   $$
   
Thus, the value of $$\cos 30^{\circ}$$ is $$\frac{\sqrt{3}}{2}$$.
$$\cos 30^{\circ} = \frac{\sqrt{3}}{2}$$.
