<ABD+<DBC=180 because they are supplementary angles.

180-<DCB-<BDC=<DBC because the sum of all the angles in a triangle is 180.

Combine these equations and solve for n:

<ABD+180-<DCB-<BDC=180

4n+6+180-60-2n=180

*Combine like termsI

2n+126=180

*Subtract 126 from both sides*

2n=54

*Divide both sides by 2*

n=27

Plug in 27 for n to calculate <ABD:

4(27)+6

<ABD=114

Hope this helps!!
