The answer is a. 5. Good luck
We can find m∠BCD like follows: m∠BCD=90°-45°=45<span>°
Now, m</span><span>∠DBC= 180°-(90°+45°)=45°
Remember that </span>

, so

We know that hypotenuse= BC= 3in and

=∠DBC)=45°, so replacing the values we get:

We can conclude that the segment CD is 2.12 in
Answer:
108 rooms
Step-by-step explanation:
Robin can clean 72 rooms in 666 days
means in 666 days rooms that can be clean is 72 rooms
in 1 days rooms that can be clean is 72/666 rooms
in 999 days rooms can be clean is 999\times 72\div 666
after solving we get 108 answer
