Answer:

m∠2 = 67°

Explanation:

m║n ⇒ (9x + 2)° = 74° {Corresponding Angles}

(9x)° = 72°

x = 8

Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)

(5×8 - 1)° + 74° + m∠2 = 180°

39° + 74° + m∠2 = 180°

113° + m∠2 = 180°

m∠2 = 180° - 113°

m∠2 = 67°
