{tex}\bigtriangleup{/tex}ABC,
Ext.{tex}\angle{/tex}ACD = {tex}\angle{/tex}ABC + {tex}\angle{/tex}BAC (Exterior Angle Theorem)

{tex}\Rightarrow{/tex} {tex}\angle{/tex}ABC + {tex}\angle{/tex}ACD = {tex}\angle{/tex}ABC + {tex}\angle{/tex}ABC + {tex}\angle{/tex}BAC
(Adding {tex}\angle{/tex}ABC to both sides)
= 2 {tex}\angle{/tex}ABC + {tex}\angle{/tex}BAC = 2{tex}\angle{/tex}ABC + 2{tex}\angle{/tex}BAL
(AL is the bisector of {tex}\angle{/tex}BAC)
= 2({tex}\angle{/tex}ABC + {tex}\angle{/tex}BAL) = 2{tex}\angle{/tex}ALC
(because, In{tex}\bigtriangleup{/tex}ABL, Ext.{tex}\angle{/tex}ALC = {tex}\angle{/tex}ABC + {tex}\angle{/tex}BAL) (Exterior Angle Theorem)

lcm(48,60,72)=720

so they will meet after running 720 km each Or after taking 2 rounds of field

A will take 720/48= 15 days

B will take 720/60=12 days

C will take 720/72= 10 days

Honey ??? 6 years, 10 months ago

No bcoz hcf should be factor of lcm

Anshika / U Can Call Me Alien ????? 6 years, 10 months ago

HCF of two numbers is a factor of the LCM of those numbers. Thus, we cannot have two numbers whose HCF is 16 and LCM is 380. Because, when we divide 380 by 16, we get a remainder of 12. Thus, 16 is not a factor of 380.
