Question

look at this diagram:
if \\( \overleftrightarrow { d f } \\) and \\( \overleftrightarrow { g i } \\) are parallel lines and \\( m \angle i h e = 58 ^ { \circ } \\), what is \\( m \angle g h j \\)?
\\( \circ \\)

Explanation:

Step1: Identify vertical angles

Vertical angles are equal. Since \(\angle IHE\) and \(\angle GHJ\) are vertical angles.

Step2: Use the property of vertical angles

By the vertical - angles theorem, if \(m\angle IHE = 58^{\circ}\), then \(m\angle GHJ=m\angle IHE\)

Answer:

\(58\)
