Answer:
Explanation:
Use the property of angle bisector:
- 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.
Using the above and the diagram we can see:
and
Also we have:
From the first equation we find:
And from the second equation we get:
Substitute b in the third equation:
- 8/7c + c = 6
- 15/7c = 6
- c = 42/15 = 2.8
Then, find b:
