Question

consider following parallelogram ABCD find the value of XYZ​

Answer 1

Answer:

X = 110 degree

Y = 70 degree

Z = 70 degree

Step-by-step explanation:

angle ECF = 180 -30-40 = 110 degree (Bcoz summation of all angles of a triangle is 180 degree )

X = angle bcd= angle ECF = 110 degree ( by vertically opposite angles )

Y = angle ADC = 180 - angle BCD= 180-110=70 degree ( by interior angles )

Z = Y (by corresponding angles )
