$180°-\left(5°+90°\right)=85°$
$\left(180°-\left(90°+7\right)\right)82{,}6°$
$85°-82{,}6°=2{,}4°$
$180-\left(5°+2{,}4°\right)=172{,}6°$
$\frac{500}{\sin2{,}4}=\frac{y}{\sin172{,}6}$
$\sin2{,}4y=64{,}397...$
$y=1537{,}833...\approx1538\left(m\right)$
$\frac{1538}{\sin90}=\frac{x}{\sin5}$
$\sin90x=134{,}045...\approx134\left(m\right)$
