Question

if ab is parallel to cd , find the value of x,y,z
​

Answer 1

angle C = angle x = 70 degrees (alternate interior angles)

angle D = angle z = 50 degrees (alternate interior angles)

angle y = 180 - [angle x+angle z] (sum of all the angles forming a line =180 degrees)
=> angle y = 60 degrees

.: angle x= 70 degrees
angle y = 60 degrees
angle z = 50 degrees

Answer 2

Y=60, X=70, Z=50

Step-by-step explanation:

Angle Y=70+50+y=180(Angle sum property)

=120+y=180

y=180-120

y=60

Angle Z=50(Alternate Interior angles are equal)

Angle X=70(Alternate Interior angles are equal)
