Question

solve for x.

Explanation:

Step1: Identify angle relationship

Lines \( CD \) and \( EF \) are parallel, and \( AB \) is a transversal. So \( (4x + 3)^\circ \) and \( 103^\circ \) are corresponding angles (or alternate exterior angles, etc.), so they are equal. Thus, \( 4x + 3 = 103 \).

Step2: Solve for \( x \)

Subtract 3 from both sides: \( 4x = 103 - 3 = 100 \).
Divide both sides by 4: \( x = \frac{100}{4} = 25 \).

Answer:

\( 25 \)
