For this case we propose a system of equations:
x: Variable that represents the amount of hours that Olivia's mother drove
y: Variable that represents the amount of hours that Olivia's father drove
So, we have:
From the first equation we have:
Substituting in the second equation:
Thus, Olivia's father drove 3 hours.
Olivia's mother drove 11 hours.
Answer:
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
Now, m</span><span>∠DBC= 180°-(90°+45°)=45°
Remember that </span>
We know that hypotenuse= BC= 3in and
We can conclude that the segment CD is 2.12 in
