[Right Triangles Only] SOHCAHTOA [Right Triangles Only] cosθ = adjacent over hypotenuseStep-by-step explanation:
Step 1: Identify
Angle θ = 25°
Adjacent Leg = 4
Hypotenuse = AB
Step 2: Solve for AB
Substitute in variables [cosine]: sin25° = 4/AB[Multiplication Property of Equality] Multiply AB on both sides: ABsin25° = 4[Division Property of Equality] Isolate AB: AB = 4/sin25°Evaluate: AB = 9.46481Round: AB ≈ 9.46Ответ:
