PLEASE FIND THE ATTACHED PHOTOGRAPH FOR THE FIGURE.

SOLUTION:

  • Given, BD bisects Angle ABC.
  • So, Angle ABD = Angle CBD
  • Measure of Angle ABD = 9x-7
  • Measure of Angle CBD = 6x+2
  • Therefore,

Angle ABD = Angle CBD

or, 9x-7 = 6x+2

or, 9x-6x = 2+7

or, 3x = 9

or, x = 9 ÷ 3

or, x = 3

  • So, x = 3
  • Measure of Angle ABC

= Measure of Angle ABD + Measure of Angle CBD

= [(9x-7)+(6x+2)]°

= [(9×3-7)+(6×3+2)]°

= [27-7+18+2]°

= 40°

ANSWER:

x = 3

Measure of Angle ABC = 40°.

Hope it helps you.
