Question

Can this be 80 degree because of linear pair.
Please Help Me ​

Answer 1

Answer:

x will be not 80

use exterior angle property

Answer 2

Answer:

x = 45°

Step-by-step explanation:

y + 125° = 180° (Linear pair)

y = 180° - 125°

y = 55°

z + 100° = 180° (Linear pair)

z = 180° - 100°

z = 80°

Angle sum property of triangle

x + 80° + 55° = 180°

x + 135° = 180°

x = 180° - 135°

x = 45 °
