[Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify

Angle θ = 50°

Opposite Leg = 7

Adjacent Leg = BC

Step 2: Solve for BC

Substitute in variables [tangent]:                                                                     tan50° = 7/AC[Multiplication Property of Equality] Multiply AC on both sides:                   ACtan50° = 7[Division Property of Equality] Isolate AC:                                                      AC = 7/tan50°Evaluate:                                                                                                           AC = 5.8737Round:                                                                                                               AC ≈ 5.87
