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°
