Question

lines and angles question

Answer 1

angle A is epual to 2nd anlgle of triangle made in m line then by external property of triangle
outer angle is equal to the sum of opposite angle
x=40+65
x=105°

Answer 2

Let C be the point on which transversal intersects the line m.
Angle A = Angle C.       (Alternate interior angles)
Angle C=65°.
Angle C + Angle D=Angle x           (exterior angle property)
65°+40°=x°
105°=x°
∴ Value of angle x is 105°
