Answer 1

Answer:

$\sin(θ) = \frac{x}{y}$

$sin²θ+cos²θ=1$

$cos²θ=1-sin²θ$

$cos²θ= 1 - {( \frac{x}{y} )}^{2}$

$cos²θ = 1 - \frac{ {x}^{2} }{ {y}^{2} }$

$cos²θ = \frac{ {y}^{2} - {x}^{2} }{ {y}^{2} }$

$cosθ = \sqrt{\frac{ {y}^{2} - {x}^{2} }{ {y}^{2} } }$

$cosθ = \frac{ \sqrt{ {y}^{2} - {x}^{2} } }{y}$
