Question 226642
m angle ABC = 7x,,,,,,bisector  = 1/2 * 7x = 3.5 x
.
But  bisector  is  angle  ABD which  is  (3x+25)
.
setting  these  equal,,,,,3.5x = 3x+25,,,,,.5x=25,,,,,x=50
.
angle ABD = (3x+35) = 175 degrees,,,,,and  bisector  = 3.5(50) = 175 degrees
.
.
Angle  DBC is  also  a  bisector,,,therefore  it  also  is  175 degrees
.
