• [Right Triangles Only] SOHCAHTOA
• [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify

Angle θ = 35°

Opposite Leg BC = x

Adjacent Leg AC = 2

Step 2: Solve for x

1. Substitute [Tangent]:                    tan35° = x/2
2. Isolate x:                                        2tan35° = x
3. Rewrite:                                          x = 2tan35°
4. Evaluate:                                        x = 1.40042
5. Round:                                            x ≈ 1.40

Answer 2

Tangent (Angle) = Opposite side / adjacent side

Tangent(35) = BC/2

Multiply both sides by 2:

BC = 2 x Tangent(35)

BC = 1.40042

Rounded to nearest hundredth:  BC =  1.40
