Question

find the measures of 'x' in the following figure.​

Answer 1

Answer:

X=130°

is the correct answer

Answer 2

Answer:

Angle A

Exterior angle + Interior angle =180°

160° + Interior angle = 180°

Interior angle = 180° - 160°

Interior angle = 20°

Angle C = 110°

As the sum of measures of all interior angles of a triangle = 180°

=> 20° + Angle B° + 110°= 180°

=> Angle B° + 130° = 180°

=> Angle B° = 180° - 130°

=> Angle B° = 50°

Exterior angle + Interior angle =180°

x° + 50° = 180°

x° = 180° - 50°

x° = 130°

Hope it helps~~~~
