In the diagram ABD and BDC are supplementary, the measure of EDF = 9x, and the measure of ABD = (2x + 105).
Based on this information, which equation can be used to find the value of x?

Options:
1. 9x=2x+105
2. 2x+105+9x=180
3. 2x+105+9x=80
4. 2x+106-9x=90

Answer:

2) 2x + 105 + 9x = 180

Step-by-step explanation:

∠BDC = ∠EDF   { vertically opposite angles are equal}

∠BDC = 9x

∠ABD + ∠BDC = 180   {supplementary}

2x + 105 + 9x = 180
