Answer 1

hey dear

we know opposite sides of parallelogram are equal.

so, angle PSR = 110°

now angle PSR and angle PST forms linear pair which their sum is equal to 180°

therefore, angle PST + angle PSR = 180°

angle PST = 180° - 110°

angle PST = 70°

HERE'S UR ANSWER

Answer 2

Answer:

70°

Step-by-step explanation:

$\angle RQP + \angle QPS = 180 degrees$

= 180 - 110 = 70°

now... $\angle PST = \angle QPS$ = 70° using a property in the chapter of congruency

therefore.. the answer is 70°
