Answer 2

Answer:

In triangle QTR,

angle ( T+ Q+ R) = 180° ( Angle sum property of a triangle)

=90° + 40° + x = 180°( given )

=130°+ x = 180°

=x = 180° -130°

=x=50°

Consider triangle PRS,

angle (P + R ) = angle S ( Sum of any two interior opposite angles of a triangle is equals to the exterior angle)

30° + x = S

30° +50° = y

80° = y
