Question

of cos o = 0.6 show that (5 sino-3 tano =0​

Answer 1

Answer:

We know : cos o=0.6=6/10=3/5

5 sin o-3 tan0 =0  (To prove)

L.H.S

tan o=sin o / cos o

5 sin o - 3 sin o /cos o

(sin o) [5-(3/cos o)]

But cos o=3/5

(sin o)[5-3/(3/5)]

(sin o)[5-5]=0=R.H.S

Hence proved .PLEASE MARK AS BRAINLIEST.
