Question

Example If tan A=3/4, then find the value of sine A​

Answer 1

sin A = 3/5

Step-by-step explanation:

tan A = Perpendicular/Base = 3/4

We know,

sin A = Perpendicular/Hypotenuse

So, we have

Perpendicular = 3

Base = 4

Hypotenuse = ?

We know,

Hypotenuse ² = Perpendicular ² + Base²

Hypotenuse² = 3² + 4²

Hypotenuse² = 9 + 16 = 25

Hypotenuse = √25 = 5

So, sin A = 3/5
