Question

answer attempt 1 out of 2

x =

y =

Explanation:

Step1: Use the property of parallelogram (opposite sides are equal)

For the sides with expressions involving \(x\): \(x + 5=78\)

Step2: Solve the equation for \(x\)

Subtract \(5\) from both sides: \(x=78 - 5\)

Step3: Use the property of parallelogram (opposite sides are equal)

For the sides with expressions involving \(y\): \(-y + 8=140\)

Step4: Solve the equation for \(y\)

First, subtract \(8\) from both sides: \(-y=140 - 8\), so \(-y = 132\). Then multiply both sides by \(- 1\): \(y=-132\)

Answer:

\(x = 73\), \(y=-132\)
