angle that crosspondst/_1.​

Answer 1

${\huge{\pink{↬}}} \:  \: {\huge{\underline{\boxed{\bf{\pink{Answer}}}}}}$

Using corresponding angles and straight angles, find the measures of the angles formed by the intersection of parallel lines m and n cut by transversal l below. ∠2 ≅ ∠60° since they are corresponding angles, and m and n are parallel. ∠1 and ∠2 form a straight angle, so∠1=120°.
