Uses of Sin Cos Tan We can calculate Sides and Angles values by using Sin, Cos and Tan formula.

let see how …

**here we will calculate a degree value by using Sinθ.**

Sinθ = p/h (this is formula)

Sinθ = 50/78.10 θ

= Sin-¹(50/78.10)

θ = 39.80°

## Uses of Sin Cos Tan

**Now, we will find out a value by using Cosθ.**

let here θ = a

Cosθ = b/h

Cosθ = 60/78.10

θ = Cos-¹(50/78.10)

θ = 39.80°

**Now, we will find out a degree value by using Tanθ so.**

let here

**θ = a**

Tanθ = p/b

Tanθ = 50/60

θ = Tan-¹(50/60)

θ = 39.80°
