Question

work it out
solve for x.

Explanation:

Step1: Use the property of vertical angles

Vertical angles are equal. Here, \(103^{\circ}\) and \(4x + 3\) are vertical angles. So, \(4x+3=103\).

Step2: Solve the equation for \(x\)

Subtract \(3\) from both sides of the equation: \(4x=103 - 3\), which simplifies to \(4x = 100\).
Then divide both sides by \(4\): \(x=\frac{100}{4}\).

Answer:

\(x = 25\)
