Answer:
♡HELLO♡
if \: \alpha \: is \: the \: angle \: made \: by \: umbrella \: with \: horizontal \: then \: tan \alpha = vr \div vmifαistheanglemadebyumbrellawithhorizontalthentanα=vr÷vm
IN THE GIVEN PROBLEM,
Vrm =1.5x =3x/2
Vm =x
Vr =?
vrm {}^{2} = vr {}^{2} + vm {}^{2}vrm
2
=vr
+vm
vr {}^{2} = 9x {}^{2} - 4x {}^{2} \div 4vr
=9x
−4x
÷4
= 5x^2 /4
Vr = root5 x/2
so now, Tan a = Vr/m = root5/2
{\boxed{Angle = tan^-1 ×2/root5}}
Angle=tan
−
1×2/root5
HOPE IT HELPS :)
we will be alive (՞ټ՞)
