Answer:

The answer will be 3 cm

Step-by-step explanation:

Because

LB is a bisector on the segment AC

so it will divide the line of AC in two equal parts.

AC= 5/2=2.5

therefore, AL=2.5 AND LC=2.5CM

BY ANGLE BISECTOR THEOREM,

AB/BC=AL/LC

AB/3=2.5/2.5

AB/3=1/1

THEREFORE, AB= 3cm

Answer:

Given that LB=90

AC=5m

BC=3m

Sol: We know that,

AC^2=BC^2+AB^2. ( by Pyth. theorem)

(5)^2=(3)^2+AB^2

25= 9+ AB^2

25-9=AB^2

16=AB^2

AB=√16

AB= 4m
