Answer:
Step-by-step explanation:
The angles between the parallel sides add up to 180 degrees.
So 180-70 = 110 degrees.

Let,
The unknown angle measure be x°.
We know that,
Sum of all angles of a Quadrilateral measures 360°.
So,
⇒∠QPR + ∠PSR + ∠SRQ + ∠RQP = 360°
⇒ 120° + 60° + 70° + x° = 360°
⇒ 180° + 70° + x° = 360°
⇒ 250° + x° = 360°
⇒ x° = 360° - 250°
⇒ x° = 110°
Therefore, the names of the angles & their values will be,
⇒∠QPR = 120°
⇒∠PSR = 60°
⇒∠SRQ = 70°
⇒∠RQP = 110°
