Answer:
D. Opposite angles are congruent
With option A, we can see that it is clearly wrong, in a parallelogram, only the opposite sides are congruent, if all of the sides are congruent then the shape is more likely to be a square or a rhombus.
With option B, only the opposites angles are congruent. If all four angles are congruent, that will be more likely to be true when we consider a square or a rectangle.
With option C, it is also wrong, unless the shape is a rhombus, square or rectangle.
That leaves us with the last option which is D.

Answer:
Step-by-step explanation:
Let the speed of the current be c
<u>Time upstream is</u>
<u>Time downstream is</u>
<u>Total time is 8 hours</u>
- 55/(16 + c) + 55/(16 - c) = 8
- 55(16 -c + 16 + c)/(16 + c)(16 - c) = 8
- 55*32= 8*(16² - c²)
- 220 = 256 - c²
- c² = 36
- c = 6 mph
