Question

in the figure p||q and r is the transversal find unknown angles.​

Answer 1

Answer:

angle b = 125°

angle f = angle d = angle b =125°

angle a=(180-125)

=55°

angle a = angle e = angle g= 55°

Step-by-step explanation:

angle f = angle d = angle b { vertically opposites angles}

angle a = angle e = angle g { vertically opposite angles}

Answer 2

Answer:

b = 123° ( vertically opposite angles)

angle b + angle e = 180° ( co-interior angles)

=> 123° - angle e = 180°

=> angle e = 180° - 123°

=> angle e = 57°

angle g = 57° ( vertically opposite angles)

angle c = 57° (alternate angles)

angle d = 123° ( alternate angles)

angle f = 123° ( vertically opposite angles)

angle a = 57° (vertically opposite angles)
