Question

what is ( mangle 1 )?( mangle 1 = square^circ )when a transversal intersects parallel lines, the corresponding angles are congruent.an error has occurred. please enter a number.

Explanation:

Step1: Identify corresponding angle

The angle corresponding to $\angle 1$ is the $98^\circ$ angle on the lower parallel line, as they occupy matching positions relative to the transversal and parallel lines.

Step2: Apply congruent corresponding angles

Since corresponding angles of parallel lines cut by a transversal are congruent, $m\angle 1$ equals the measure of its corresponding angle.
$m\angle 1 = 98^\circ$

Answer:

$98$
