Question

find the value of x,y,and z if Ac and EF are parallel <ADB=?​

Answer 1

Answer:

Since AC and EF are parallel

therefore, 80° + X° = 180°

X° = 180° - 80°

[ X° = 100°]

Now, In Triangle ADB

30° + 90° + Y° = 180° [sum of all angles in a triangle]

Therefore, Y° = 180° - 120° = 60°

[Y° = 60°]

Since, AC is a straight line

Therefore, 60° + Z° + 80° = 180° [By linear pair axiom]

Z° = 180° - 140°

[Z° = 40°]

X = 100° , Y = 60° , Z = 40°
