3.2 extra practice
in exercises 1 and 2, find m∠1 and m∠2.
1.
in exercises 3 and 4, find the value of x. show your st

1. (3x - 8)°

Explanation:

Step1: Identify angle - relationship for ∠1

The 41° angle and ∠1 are corresponding angles. Corresponding angles formed by parallel lines and a transversal are congruent.
$m\angle1 = 41^{\circ}$

Step2: Identify angle - relationship for ∠2

The 41° angle and ∠2 are alternate - interior angles. Alternate - interior angles formed by parallel lines and a transversal are congruent.
$m\angle2 = 41^{\circ}$

Answer:

$m\angle1 = 41^{\circ}$, $m\angle2 = 41^{\circ}$
