Question

anyone answer my question

Answer 1

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
