[Right Triangles Only] SOHCAHTOA[Right Triangles Only] cosθ = adjacent over hypotenuse

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]:                                                                     [Multiplication Property of Equality] Isolate x:                                               Rewrite:                                                                                                           Evaluate:
