$s ≅ 11, 31$ $s~=11,31$

Explanation:

$x_{1} = 12 \cdot cos (- 3 \frac{π}{4}) x_{1} = 8, 485$ $x_1=12*cos(-3pi/4)" "x_1=8,485$
$y_{1} = 12 \cdot sin (- 3 \frac{π}{4}) y_{1} = - 8, 485$ $y_1=12 *sin (-3pi/4)" "y_1=-8,485$
$x_{2} = - 1 \cdot cos π = 1$ $x_2=-1*cos pi=1$
$y_{2} = - 1 \cdot sin π = 0$ $y_2=-1*sin pi=0$
$s = \sqrt{{(7, 485)}^{2} + {(- 8, 485)}^{2}}$ $s=sqrt((7,485)^2+(-8,485)^2)$
$s = \sqrt{56, 025225 + 71, 995225}$ $s=sqrt(56,025225+71,995225)$
$s = \sqrt{128, 02045}$ $s=sqrt (128,02045)$
$s ≅ 11, 31$ $s~=11,31$
