Answer 1

Answer:

In figure PQRS

angleSPQ+anglePQR+angleQRS+angleRSP= 360°. [angle sum property of a quadrilateral]

100°+anglePQR+70°+85°=360°

anglePQR=105°=anglePQS+angleSQR

40°+angleSQR=105°

angleSQR=65°

angleSQR=angleQRT [alternate interior angles]

therefore X=65°

Explanation for angle sum property of a quadrilateral:

This property states that the sum of all the interior angles of a quadrilateral is 360°
