In Fig. 6.35, QP || RT. Find the values of x and y.


Answer :

Given: QP || RT


Formula Used/Theory:-


Angle sum property


Sum of all angles of triangle is 180°


if lines are parallel then alternate angles are equal


AS QP || RT


And PR is transverse


x = 70° Alternate angles


By angle sum property


x + y + 30° = 180°


70° + y + 30° = 180°


Y + 100° = 180°


y = 180° - 100° = 80°


Result:- x = 70°; y = 80°
