Answer:
m∠FXM = 24°
Step-by-step explanation:
This problem has a lot of extra data that has no relation to the question. You can basically ignore any business about isosceles triangles and congruent segments.

The only thing you need to know is the angle sum theorem:
m∠FXM + m∠MXA = m∠FXA
Filling in the numbers, you get ...
m∠FXM + 72° = 96°
m∠FXM = 96° -72° = 24°
The measure of angle FXM is 24°. (matches choice A)
Recall your d = rt, distance = rate * time.
let's say the boat has a still water rate of "b", and the current has a a rate of "c", ok.... when the boat is going upstream, is not really going "b" fast, is going slower at "b - c", due to the current going in the opposite direction.
when the boat is coming downstream, is not going "b" fast either, is going faster, is going "b + c", due to the current adding speed to it.
we know the trip up was 108 kms, thus the return trip is also 108 kms.

and surely you know how much that is.
what's the boat's speed? well, 36 + c = b.
R(s+t) = rs + rt represents Distributive Property because r is multiplying s and t
i.e. ( r*s + r*t )
= rs + rt
So correct answer is Distributive Property.
hope this helps :)
Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
