Answer

x=2 and y=2√2

Step-by-step explanation:

$\sin( \alpha ) = \frac{2 \sqrt{2} }{x } \\ x = \frac{2 \sqrt{2} }{ \sin(45) } \\ x = 4 \\ {x}^{2} = {y}^{2} + 2 \sqrt{2} \\ {4}^{2} = {y}^{2} + (2 \sqrt{2 \: )}^{2} \\ 16 = {y}^{2} + 8 \\ 16 - 8 = {y}^{2} \\ y = \sqrt{8} \\ y = 2 \sqrt{2}$

Plz solve i beg i really need help i beg u guys

Dmitry_Shevchenko [17]

check the picture below.

if ∡F = 90° and ∡D = 30°, then the ∡A = 60°, meaning the triangle is a 30-60-90 triangle and therefore we can use the 30-60-90 rule as you see in the picture.

$\bf \textit{area of a triangle}\\\\
A=\cfrac{1}{2}bh~~
\begin{cases}
b=base\\
h=height\\[-0.5em]
\hrulefill\\
h=7\sqrt{3}\\
b=7
\end{cases}\implies A=\cfrac{1}{2}(7)(7\sqrt{3})
\\\\\\
A=\cfrac{49\sqrt{3}}{2}\implies A\approx 42.43524478543749369142$
