Rzqust [24]

Answer:

4.5

Step-by-step explanation:

Let the number be x

6x-14 = 40

Add 14

6x = 40+14

6x = 54

Divide by 6

6x/6 = 54/6

x = 9

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

Step-by-step explanation:

<u>Step 1: Identify</u>

Angle θ = 35°

Opposite Leg BC = <em>x</em>

Adjacent Leg AC = 2

<u>Step 2: Solve for </u><em><u>x</u></em>

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