Answer:

  • a = 8, b = 3.2, c = 2.8

Step-by-step explanation:

<u>Use the property of angle bisector: </u>

  • <em>An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.</em>

<u>Using the above and the diagram we can see:</u>

  • a/6 = 4/3

and

  • a/7 = b/c

<u>Also we have:</u>

  • b + c = 6

<u>From the first equation we find:</u>

  • a = 6*4/3 = 8

<u>And from the second equation we get:</u>

  • 8/7 = b/c ⇒ b = 8/7c

<u>Substitute b in the third equation:</u>

  • 8/7c + c = 6
  • 15/7c = 6
  • c = 42/15 = 2.8

<u>Then, find b:</u>

  • b = 6 - 2.8 = 3.2
