Answer:
A). It is a conditional statement that can be written as “If a quadrilateral has exactly one pair of parallel opposite sides, then it is a trapezoid."
B). The hypothesis is: a quadrilateral having exactly one pair of parallel opposite sides.
E). The conclusion is: it is a trapezoid.

I just did the assignment on Edge. It's 100% correct!! Hope this helps!!
Also heart and rate if you found this answer helpful.
There are 4 quarts in a gallon. 4 times 5 is 20 and 28 divided by 20 is 1.4. So the cost of one quart of the oil is $1.40
Answer:
-9.5 would be less than -9.05
Let
T = theta
Use the Law of Cosines to get
c^2 = a^2+b^2 - 2ab*cos(T)
<span>7^2 = 10^2+8^2 - 2*10*8*cos(T)
</span><span>49 = 164 - 160*cos(T)
-160cos(T) = 49-164
</span><span>-160cos(T) = -115
</span>cos(T) = -115/(-160)
cos(T) = 23/32
cos(T) = 0.71875 which rounds to 0.72
The final answer is C) 0.72
