Question

3. If tan x = 3/4 and x lies in the first quadrant find sin x.​

Answer 1

Answer:

3

3/5

Step-by-step explanation:

hi it's your answer good p square + 4 square = 25 square so it is equals to 5 hand sin x is equals to 3 upon 5

Answer 2

Answer:

Value of sinx is 3/5 when x lies in the first quadrent

Step-by-step explanation:

Given:

tan x= 3/4

As we know that ,tan Ф = perpendicular /base

So by compairing we get,

Perpendicular= 3, base = 4

According to pythagoras theorem ,

$(hypotenuse) ^{2} = (perpendicular)^{2} + (base)^{2}$

                       = $3^{2} +4^{2}$

     hypotenuse = $\sqrt{9+16}$

                           = $\sqrt{25}$= 5

So,sin x= perpendicular/ hypotenuse

           = 3/5
