In the given figure, QP || RT. Find the values of x, y, and z.​

Answer»

Answer:

∠x = 70 °   and   ∠ y =  80°

Step-by-step EXPLANATION:

we know that if two lines are parallel then the ALTERNATE opp angles are equal so

∠ QPR= ∠PRT ===>  ∠x = 70 °

now , QPR is forming a triangle and angle SUM property of triangle SAYS that sum of all  interior angles of triangle is 180 °

so,

       30° + 70° + ∠y = 180°

         ∠ y =  180° - 100° = 80°
