Question

if $fh = y$ and $fj = 2y - 36$, find $fj$ in parallelogram $ghij$.
$fj = \square$

Explanation:

Step1: Usar propiedad de paralelogramo

En un paralelogramo, las diagonales se bisecan, así que $FJ = FH$.

Step2: Igualar expresiones y resolver $y$

$$y = 2y - 36$$
$$36 = 2y - y$$
$$y = 36$$

Step3: Calcular $FJ$

Sustituir $y=36$ en $FJ = 2y - 36$:
$$FJ = 2(36) - 36$$

Answer:

$36$
