Question 1062499
.
ABC is a triangle its perimeter is 27cm. BD ia a straight line that biscect angle B and intersects AC line segment at D if : AD=4cm and CD = 5cm 
Find lenght of :AB BC and BD line segments 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Use this <U>HINT</U>: 


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In a triangle, the angle bisector divides the side to which it is drawn, in two segments 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;proportional to the ratio of two other sides of a triangle.


Regarding this statement, see the lesson

<U>Comment from student</U>: Thankyouuu! I tried and I solved it but I don't think it is right AB = 10 and BC = 8?
-------------------



<U>My response</U>:  AB = 8,  BC = 10.
