Look at all the steps above. They lead to a double solution. The symbol

x=\pm 5

means that x can be either positive or negative 5. You can't accept negative values for lengths, so you're left with one option only.

M<br> (9x + 2)<br> 1<br> (5х – 1)°<br> 740<br> What is mz2?<br> 39°<br> 570<br> ОООО<br> 67°<br> 740
Elodia [21]

Answer:

<h3>           m∠2 = 67°</h3>

Step-by-step 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°
