Answer:
3 hours and 51 minutes
Step-by-step explanation:
Take the ending time and subtract the start time
3:13pm - 11:22am
Remember that pm means aft 12 o'clock in the after noon so add 12 hours
12+3:13 - 11:22
15:13 - 11:22
We are subtracting more minutes than we have so we have to borrow from the hours
1 hour = 60 minutes
14 : 60+13 - 11:22
14:73 - 11:22
3: 51
3 hours and 51 minutes

Answer:
x = 10·cos(θ) -4·cot(θ)
Step-by-step explanation:
Apparently, we are to assume that the horizontal lines are parallel to each other.
The relevant trig relations are ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
If the junction point in the middle of AB is labeled X, then we have ...
sin(θ) = 4/BX ⇒ BX = 4/sin(θ)
cos(θ) = x/XA ⇒ XA = x/cos(θ)
Then ...
BX +XA = AB = 10
Substituting for BX and XA using the above relations, we get
4/sin(θ) +x/cos(θ) = 10
Solving for x gives ...
x = (10 -4/sin(θ))·cos(θ)
x = 10·cos(θ) -4·cot(θ) . . . . . simplify
_____
We used the identity ...
cot(θ) = cos(θ)/sin(θ)
