= 351π.
Answer:
x = 30
y = 15
Step-by-step explanation:
<u><em>All the angles are </em></u><u><em>90°</em></u><u><em>, so set 6y and 3x equal to 90, like so:</em></u>
6y = 90
<u><em>Divide both sides by 6:</em></u>
y = 15
<u>Solving for x:</u>
3x = 90
<em><u>Divide both sides by 3:</u></em>
x = 30
Answer: B. 15
