Lines m and n are parallel. what is the measure of angle 5? 42 48 132 180

∠5 = 48°

Step-by-step explanation:

Since we are given that m is parallel to n

Refer the attached figure

Since ∠8 = 132°

And ∠8 = ∠4 (alternate interior angles are equal)

Thus ∠4 = 132°

Now, ∠4+∠5=180° (sum of linear pairs is 180°)

⇒132°+∠5=180°

⇒∠5=180°-132°

⇒∠5=48°

Hence ∠5 = 48°
