Answer 1

Answer:

x° = 100°

Step-by-step explanation:

In triangle ROT, by Angle sum property of a triangle

140° + a° + b° = 180°

=> a° +b° = 180° – 140°

=> a° +b°= 40° ——( eq.1 )

In triangle RST, by Angle sum property of a triangle

x°+ a° +b°+ a° +b° = 180°

x° +2a° + 2b°= 180°

x° +2(a° +b°) = 180°

x° +2(40°) = 180° ( From eq.1)

x° +80° = 180°

x° = 180° – 80°

x° = 100°

Hope it helps you dude.
