Step-by-step explanation:

Step 1: Identify Variables

Angle θ = 30°

Adjacent Leg = x

Hypotenuse = 8

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(30^\circ) = \frac{x}{8}$
[Multiplication Property of Equality] Isolate x: $\displaystyle 8cos(30^\circ) = x$
Rewrite: $\displaystyle x = 8cos(30^\circ)$
Evaluate: $\displaystyle x = 4\sqrt{3}$
