Question

solve the given question​

Answer 1

Step-by-step explanation:

$sin^{2} \alpha + \cos^{2} \alpha = 1$

Answer 2

Answer:

√3/√3 +2

Step-by-step explanation:

cot Ф = 1/tanФ

Also sin^2Ф+cos^Ф =1

(sin^2Ф+cos^Ф)/1+cotФ= 1/1+cotФ

⇒tanФ/1+tanФ

given cotФ =2/√3 ⇒tanФ = √3/2

on substituting tan value in the above, we get, √3/√3 +2
