Question

answer in answer sheet - x=60 degree, y = 30 degree,z = 15 degree​

Answer 1

Answer:

x=60°   y=30°   z=150°

Step-by-step explanation:

Since AB║CD and AE║CF, ∠120 and ∠x are supplementary angles,

hence 120°+x=180°

           x=180°-120°=60°

Since ∠x , ∠y , ∠90 are supplementary angles,

         x+y+90°=180°                 we know that x=60°

        y+150°=180°

         y=180°-150°=30°

Since ∠z and ∠y are supplementary angles,

     z+y=180°                  we know that y=30°

     z+30°=180°

    z=180°-30°=150°

Hence, x=60°   y=30°   z=150°
