Question

tanA=3/4 then cosA and sinA​

Answer 1

Answer:

sinA=3 and cosA=4

Step-by-step explanation:

tanA=sinA/CosA

tanA=3/4

so,

sinA=3 and cosA=4

Answer 2

CosA=4/5

SinA=3/5

.

Step-by-step explanation:

tanA= 3/4

p/b=3/4

.

p=3

b=4

h=?

h=√(3^2+4^2)

h=√(9+16)

h=√25

h=5

.

hence,cosA= b/h=4/5

and,sinA=p/h=3/5
