Answer:
see explanation
Explanation:
(3)
Opposite angles are congruent , so
9x - 5 = 103 (add 5 to both sides )
9x = 108 ( divide both sides by 9 )
x = 12
Consecutive angles are supplementary, sum to 180° then
7y + 103 = 180 ( subtract 103 from 180 )
7y = 77 ( divide both sides by 7 )
y = 11
------------------------------------------------------------------
(4)
Opposite sides are congruent, so
3x = 36 ( divide both sides by 3 )
x = 12
and
5y = 45 ( divide both sides by 5 )
y = 9
