Answer: 1 + √4 / 4
Step-by-step explanation:
according to the question we get to know that θ = 45°
anyways
2tanθ = 2sinθ / cosθ
given that sinθ = cosθ
=>2tanθ = 2sinθ / sinθ = sinθ
now we have to solve sinθ + sin²θ(as sinθ = cosθ)
θ = 45
then
sinθ = 1/√4 on rationalizing you will get √4/4
sin²θ = (1/√4)² = 1/4
if we add we will get
=> √4 / 4 + 1/4
=> 1 + √4 / 4
