Answer:

x = 44, y = 37

Explanation:

∠1 and ∠ 4 are adjacent angles and are supplementary, thus

3x + 4 + x = 180

4x + 4 = 180 ( subtract 4 from both sides )

4x = 176 ( divide both sides by 4 )

x = 44

------------

∠ 1 and ∠ 3 are vertical angles and congruent, thus

4y - 12 = 3x + 4 = 3(44) + 4 = 132 + 4 = 136 ( add 12 to both sides )

4y = 148 ( divide both sides by 4 )

y = 37
