Answer 1

Answer:

  60° + x +x-20 = 180°

   40° + 2x       = 180°

             2x      = 180° - 40°

             2x       =  140°

                   x     = 140° ÷2

                          = 70°

∴x - 20° = 70 ° - 20° = 50 °

Step-by-step explanation:

by angle sum property

x-20 is smallest ∠ which is = 50°
