Question

Work out the size of angle x.

Answer 1

Answer:

x = 13°

Step-by-step explanation:

angle p +  98°  = 180°          [angles on a straight line add up to 180°]

         p = 180° -  98°

         p = 82°

angle q = 85°                       [alternate angles with the 85° angle]

Inside the yellow triangle:

p + q + x =  180°                   [angles inside a triangle add up to 180°]

82° + 85° + x = 180°

x = 180° - 82° - 85°

∴   x = 13°
