Question

in the following figure ab is parallel to CD and CD is parallel to EF find the value of X Y and Z with the process​

Answer 1

Answer:

i) x = 113°  ;  y= 12°  ; z = 79°

ii) z= 67°

Step-by-step explanation:

i) Co-interior angles are spplementary

 i.e, their sum is = 180°

⇒  67+x = 180°

⇒  x =180-67

⇒  x = 113°

alternate interior angles are equal

i.e,  z= 79°

corresponding angles are equal

 i.e, 67°+ y = z

   ⇒ y = z- 67°

   ⇒ y = 79-67

   ⇒ y = 12°

ii) alternate exterior angles are equal.

  so, z= 67°
