Question

find the value of the unknown exterior angle x of 30 and 40 degree and 60 and 60 and 50 and 50 and 30 and 60 step by step

Answer 1

Answer:

exterior angle = 180 (Angle sum property)

so angles are

x=180-40+30

=180-70=110

x=180-60+60

=180-120=60

x=180-50+50

=180-100=80

x=180-30+50

=180-90=90
