Answer:
x = 2
y = 29
Step-by-step explanation:
<u><em>2x + 9 and x + 11 are sides that are congruent to one another, so set them equal, like so:</em></u>
2x + 9 = x + 11
<u><em>Subtract x from both sides:</em></u>
x + 9 = 11
<u><em>Subtract 9 from both sides:</em></u>
x = 2
<u>Solving for y</u>, the opposite angles are congruent to one another, so set them equal, like so:
3y + 19 = 106
<em><u>Subtract 19 from both sides:</u></em>
3y = 87
<em><u>Divide both sides by 3:</u></em>
y = 29
