Question

in the given figure q||r, angle 1 = 85° find angle 2 angle 3 angle 4 angle 5 angle 6 angle 8?

Answer 1

angle 1=85deg
therefore
angle 3=angle1=85deg (vertical opposes angles)
angle 5=angle3=85deg (alt into. and)
ang7=ang5=85deg (vert. opposite. any)
and 7+ang8=180deg (linear pair of anger)
85deg +ang8=180
ang8=180-85 =95deg
and 6=ang8=95deg(vert opposes angles)
ang4=ang6=95deg(alt int and)
ang2=ang4=95deg(vert .opp)
