Find tita in the figure​

Answer»

Answer:

60°.

Step-by-step EXPLANATION:

 Using the terms and PROPERTIES of trigonometry:

Here,

tanθ = AB / BC

⇒ tanθ = 15 / 5√3

⇒ tanθ = 3 / √3

⇒ tanθ = √3

     Using table, we can say tan60° = √3

Therefore,

⇒ tanθ = tan60°

⇒ θ = 60°

  Hence the REQUIRED value of theta is 60°.
