Question

SinA=4/5 Hai to TanA ka man hoga​

Answer 1

Answer:

sinA = 4/5 = p/h

(h)2 = (p)2+(b)2

(5)2 = (4)2+ (b)2

25 = 16+b2

b2 = 9

b = 3

tanA = P/b = 4/3

Answer 2

Answer:

tanA=4/3

Explanation:

cos2+sin2=1 ___(1)

given , sin = 4/5____(2)

sin2=16/25

from____(1)

cos2+16/25=1

cos2=1-16/25

cos2=9/25

cos=3/5______(3)

tan=sin/cos

from____(3)&_____(2)

tan=4/5÷3/5

tan=4/3

ANS...4/3
