Question

Given:cos a =0.6; find all other trignometrical ratios for anglea

Answer 1

cos a = base/ hypo = 6/10= 3/5
so p = sqrt(sq(5)- sq(3))
p = sqrt(25-9)
p =4
so sina = 4/5 ....coseca = 5/4
tana = 4/3 ......cota = 3/4
sec a = 5/3

Answer 2

Hey....here is ur answer ⤵
Given..
cosA=0.6=6/10=3/5
It means....base=3 and hypotenuse=5
so the lenght of perpendicular=4 (by pythagoros theorem)
now...
sonA =4/5
tanA=4/3
cotA=3/4
secA=5/3
cosecA=5/4

I hope it helps you☺
