Answer:

x = 53

Step-by-step explanation:

AB ║ CD                         Given        

m ∠APQ = m ∠RQP = 62°       If parallel lines, then alternate interior angle =

  m ∠DRP + m ∠PRQ = 180°   These angles form a linear pair which = 180°

         115° + m ∠PRQ = 180°      Substitution

  m ∠PRQ = 65°                  Subtraction  

m Δ QPR = 180°                       Definition of triangle

m Δ QPR = m ∠PQR + m ∠QPR + m ∠PRQ    the sum of the angles of triangle

    180° =  62° +  x  + 65°

    180 =  127 +  x

    53 = x
