BD bisects ABC Find mZABD, mZCBD, and mZABC. (3x + 6) D B (7x 38 18) mLABD x 33 X m_CBD 136 x x MZ ZABC12 x x

Answer:
when a line bisectes a angle it divides the angle into 2 equal parts.
angle abd=angle cbd
(3x+6)°=(7x-18)°
6+18=7x-3x
24=4x
24/4=x
6=x
angle abd=(3x+6)°
by putting value of x.
3×6+6
angle abd=24°
angle cbd=(7x-18)°
7×6-18
angle cbd=24°
angle abc=24°°+24°
angle abc =48°
