Question

note: you can assume all figures are parallelograms. value: 2 solve for x. a. 7 b. 15 c. 3 d. 18

Explanation:

Step1: Use property of parallelogram

In a parallelogram, the diagonals bisect each other. So, the two - segment lengths given are equal, i.e., $3x - 6=15$.

Step2: Solve the equation for x

Add 6 to both sides of the equation: $3x=15 + 6$. So, $3x=21$.

Step3: Isolate x

Divide both sides of the equation $3x = 21$ by 3. We get $x=\frac{21}{3}=7$.

Answer:

A. 7
