Answer:
N.14 ABC = 5x+20, N.15 ABE = 90. N.16. 123, 29, 28. N.17 K = 80
Step-by-step explanation:
Because of vertical angles, 5x+20 = 3x+66.
5x=3x+46
2x = 46
x = 23
Sum of angles in a circle is 360
360-135-135=180
ABE = CBD because vertical angles.
180 / 2 = 90
16.
Sum of angles in triangle is 180
180=123-x-2-x-3
x = 31
123, 29, 28.
17.
Sum of angles in triangle is 180
180-72-28 = 80
K = 80
Answer:
90
Step-by-step explanation:
39+23+28=90
180-90=90
It's 640 ft^2.
If the storage is 96 ft^2 and 15% of the total amount of space is required.
X=100%
96 ft:15=x:100
Solve for x and you get 640 ft^
Answer:
Yes
Step-by-step explanation:
Because 6.3hours is still in the range 5.5+/-1.8 hours
Therefore the result support the findings of the study.
I would think that it is B. because it makes the most sense to me. it also could be B. for one other reason and that is converting helps to understand how to salve it on pencil and paper if you know how to convert on paper
so my answer would be B.
