SOLUTION

1️⃣

In ∆ABC

Y= 85° (Alternate Interior Angle)

Z= 35° (Also alternate Interior Angle)

Now,

X+Y+Z=180°(sum of the property of∆)

=) X +85° +35°= 180°

=) X+ 120°= 180°

=) X= 180° -120°

=) X= 60°

2️⃣

Given,

Given,l & m are intersected by a transversal n.

True, l parallel to m

(angle AQR will be 80° by linear pair)

Angle CRS = angle QRD=80

(Vertically opposite angles)

Thus, Angle AQR= Angle QRD

So, l||m.

hope it helps ☺️
