Question

find tensions of string T1,T2 in kgwt (cos37°=4/5,cos53=3/5)​

Answer 1

$\pink{\boxed{\boxed{\boxed{Answer:-}}}}$

:Force balancing in vertical and horizontal direction

T1 cos 30+ T2 cos 60= mg

T1 root3/2 +T2/2 =5*10

And

T1 cos 60= T2 cos 30

T1 = T2 root 3

Now put in first

T2 *3 +T2 =100

T2 =25

T1 = 25root3
