Question

In the below figure, if AB II CD, then find the value of x.​

Answer 1

Answer:

angle ace = 75°(alternate angles)

angleFCE= 180°-75°=105°( linear pair)

angle x= 180°-135°=45° ( angle sum property of a ∆)

Answer 2

Answer:

x = 45

Step-by-step explanation:

In the figure:

75 Degree = Angle DCF (Corresponding angles are equal)

Angle DCF = x+30 (Sun of 2 interior angles of a triangle is equal to the opposite exterior angle of the triangle)

or, 75 = x+30

or, x = 75 - 30

or, x = 45
