Question

if $ce = y + 1$ and $cg = 2y - 29$, find the value of $y$ in parallelogram $defg$.

Explanation:

Step1: Set segments equal (parallelogram diagonals bisect)

$y + 1 = 2y - 29$

Step2: Isolate y (subtract y from both sides)

$1 = y - 29$

Step3: Solve for y (add 29 to both sides)

$y = 1 + 29$

Answer:

$30$
