(84 - 3x)°
x =
submit

Explanation:

Step1: Identify vertical - angles

Vertical angles are equal. $\angle KOP$ and $\angle MPN$ are vertical angles. So, $78 - x=84 - 3x$.

Step2: Solve the equation for x

Add $3x$ to both sides: $78 - x+3x=84 - 3x+3x$, which simplifies to $78 + 2x=84$.

Step3: Isolate the variable term

Subtract 78 from both sides: $78 + 2x-78=84 - 78$, getting $2x = 6$.

Step4: Solve for x

Divide both sides by 2: $\frac{2x}{2}=\frac{6}{2}$, so $x = 3$.

Answer:

$3$
