Question

sem b ng quadrilaterals what is the value of y? 18 10 2y + 4 10 + 2x 3 4 5

Explanation:

Step1: Identify property of rectangle

In a rectangle, opposite - sides are equal. So, the two vertical sides are equal.
$10=2y + 4$

Step2: Solve the equation for y

Subtract 4 from both sides: $10−4=2y+4 - 4$, which simplifies to $6 = 2y$.
Then divide both sides by 2: $\frac{6}{2}=\frac{2y}{2}$, so $y = 3$.
