Answer
O = 90 deg ( Interior opposite angles )
40 deg + 90 deg + 5a = 180 deg ( Linear Pair )
130 deg + 5a = 180 deg
5a = 180 - 130
5a = 50 deg
a = 50/5
a = 10 deg
O = 90 deg ( Interior opposite angles )
40 deg + 90 deg + 5a = 180 deg ( Linear Pair )
130 deg + 5a = 180 deg
5a = 180 - 130
5a = 50 deg
a = 50/5
a = 10 deg
