The  angle  of an ( ∠a ) will measure as  45°.       What are parallel lines?   Lines  with the same  slope  and a constant  distance  between them are said to be parallel.  Two lines in the same  plane  that are equally spaced apart and never cross each other are said to be  parallel  lines.      Since ∠msr = 90°    d + c = 90°    Since d = 45°    So,    c = 45°    Since lines l and m are  parallel      So,    ∠b = 90°    Now,    a + b + c = 180°    a + 90+ 45= 180      a = 45°     Hence the  angle  will be 45°.
