Question

If 3 tan x =4 find value of sin x+cos x

Answer 1

Answer:7/5

Step-by-step explanation:

tan x = 4/3

cos x = 3/5

sin x = 4/5

six x + cos x = 7/5

Answer 2

Step-by-step explanation:

3 tan X = 4

tan X = 4/3 ( p/b)

let P = 4y

base = 3y

hypotenuse = √ 16y^2 + 9y^2 = √ 25y ^2 = 5y

sin X = ( p/h) = 4y/ 5y = 4/5

cos X = (b/h) = 3y/ 5y = 3/5

sin X + cos X = 3/5 + 4/5 = 7/5
