If Cos theta=0.6. Show that (5Sin theta-3Tan theta)=0

If Cos theta=0.6

Sol. Cos=0.6=610=35=basehypo.

Using Pythagoras Theorem, we get

AC2=AB2+BC2

52=AB2+32

25=AB2+9

AB2=25-9

AB2=16

AB=4

Sin=perp.Hypo.=45, Tan=perp.Base=43

Substituting the values in the given expression,

(5Sin-3Tan)=0

545-3454-4=0=R.H.S
