Step-by-step explanation:

<u />

<u>Trigonometric ratios</u>

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

Given:

$\theta$ = 45°
O = $x$
A = $y$
H = $3\sqrt{2}$

$\implies \sin(45^{\circ})=\dfrac{x}{3\sqrt{2}}$

$\implies x=3\sqrt{2}\sin(45^{\circ})$

$\implies x=3\sqrt{2} \cdot \dfrac{\sqrt{2}}{2}$

$\implies x=\dfrac{3\sqrt{2} \sqrt{2}}{2}$

$\implies x=\dfrac{3 \cdot 2}{2}=3$

$\implies \cos(45^{\circ})=\dfrac{y}{3\sqrt{2}}$

$\implies y=3\sqrt{2}\cos(45^{\circ})$

$\implies y=3\sqrt{2} \cdot \dfrac{\sqrt{2}}{2}$

$\implies y=\dfrac{3\sqrt{2} \sqrt{2}}{2}$

$\implies y=\dfrac{3 \cdot 2}{2}=3$
