1. The problem is to find the value of $\cos\theta$ for a given angle $\theta$. 2. The cosine of an angle in a right triangle is defined as the ratio of the length of the adjacent side to the hypotenuse: $$\cos\theta = \frac{\text{adjacent}}{\text{hypotenuse}}$$ 3. If the angle $\theta$ is known, you can find $\cos\theta$ using a calculator or trigonometric tables. 4. If you have the coordinates of a point on the unit circle corresponding to angle $\theta$, then $\cos\theta$ is the x-coordinate of that point. 5. Without additional information about $\theta$ or a triangle, the exact value of $\cos\theta$ cannot be determined. Please provide the angle $\theta$ or more context to calculate $\cos\theta$.
