Question

if 17 sin a=8 find the value of cos a and tan a​

Answer 1

Step-by-step explanation:

17sin a=8

sin a=8/17(p/h)

b=√17^2-8^2

√289-64

√225

15

cos a=b/h=15/17

tan a=p/b=8/15

Answer 2

Answer:

hope u the answer help if it help full follow me

Step-by-step explanation:

17sin a=8

sina=8/17 eq(1)

in a triangle sin a=opp/hypo eq(2)

comparing eq(1) and eq(2)

opp=8 hypo=17

pythagorous theroem

(hypo)²=(opp)²+(adj)²

from above  info

(17)²=(8)²+(adj)²

289=64+(adj)²

289-64=(adj)²

225=(adj)²

√225=adj

15=adj

hypo=17, adj=15, opp=8

cos a=adj/hypo

cos a=15/17

tana=opp/adj

tana=8/15
