Question

which equation would you use to solve for x? *
solve for x. (just put the number!!!!) *

Explanation:

Step1: Use the property of adjacent angles in a parallelogram

In a parallelogram, adjacent angles are supplementary. So, \((2x + 15)+(x + 15)=180\)

Step2: Simplify the equation

Combine like terms: \(2x+x+15 + 15=180\), which gives \(3x+30 = 180\)

Step3: Solve for \(x\)

Subtract \(30\) from both sides: \(3x=180 - 30=150\). Then divide both sides by \(3\): \(x=\frac{150}{3}=50\)

Answer:

\(50\)
