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
