Question

which angle number represents an angle vertical to ∠mrj? answer attempt 1 out of 2

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are non - adjacent angles with a common vertex and their sides are formed by the same two lines.

Step2: Identify intersecting lines and vertical angles

Lines $LP$ and $JK$ intersect at point $R$. $\angle MRJ$ and $\angle 1$ are vertical angles as they are non - adjacent, have the common vertex $R$, and their sides are formed by the intersection of lines $LP$ and $JK$.

Answer:

$1$
