Answer:
Below.
Step-by-step explanation:
Part A No. That's not the most specific shape.
Quadrilaterals can be many shapes regular and irregular.
Part B. A rectangle and a rhombus are both types of parallelogram which has 2 pairs of parallel sides. A rectangle and a rhombus are 2 specific types of parallelogram.
In the case of a rectangle it is a parallelogram with 4 right angles and a rhombus is a parallelogram with all sides equal in length,

Answer:
C) 65°
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(?) = 25/59
? = arccos(25/59) ≈ 64.93°
The indicated angle is about 65°.
_____
You can see that the figure is drawn approximately to scale and that the angle is more than 45°. (The unmarked leg is longer than the given leg.) The only answer choice that is more than 45° is the one shown above.
6x.
You cannot figure this one out, unless you know the value of x.
Hope that helped.
Answer:
The rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
Step-by-step explanation:
Given that a motorboat travels 441 kilometers in 9 hours going upstream and 388 kilometers in 4 hours going downstream, to determine what is the rate of the boat in still water and what is the rate of the current, the following calculation must be performed:
Upstream = 441/9 = 49 km per hour
Downstream = 388/4 = 97 km per hour
(97 + 49) / 2 = X
146/2 = X
73 = X
97-73 = 24
49-74 = -24
Therefore, the rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
