1 answer

To solve this problem, we need to use the properties of parallel lines and the angles formed by a transversal.

Given that JL and MO are parallel lines and \( mLKI = 116^\circ \), we can observe the configuration of angles formed when a transversal crosses these parallel lines.

Here's how we can deduce \( mONP \):

  1. Identify angles: Since JL and MO are parallel and assuming that the transversal intersects these lines, then angle LKI (which is inside the transversal lines) will have a corresponding angle formed on the opposite side of the transversal with angle ONP.

  2. Calculate \( mONP \): By the properties of corresponding angles, \( mLKI + mONP = 180^\circ \) (since they are supplementary). Therefore, we can write:

    \[ mONP = 180^\circ - mLKI \]

    Substituting the value of \( mLKI\):

    \[ mONP = 180^\circ - 116^\circ = 64^\circ \]

Thus, \( mONP = 64^\circ \).
