Answer:
Step-by-step explanation:
Tan θ = =
So, Perpendicular = b, base = a
<em><u>Finding hypotenuse by Pythagorean Theorem:</u></em>
=> So, <u><em>hypotenuse = c</em></u>
Sin θ =
Cos θ =
So, <u><em>Now finding </em></u>
=> ÷
=> ÷
=>
=>
Switch places or x and y then solve it for y and you will get the inverse of the function,let me know if u have questions
