Answer:
137 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees
180-43=137
The next three terms of -243, 81, -27, 9 is 
The given series is geometric series
<u>Solution:</u>
Given, series is -243, 81, -27, 9, …
We have to find the next three terms of the above given series.
Now, the given series can also be written as
We can say that, above series is in Geometric Progression with first term = -243 and common ratio = 
Then, next three term would be,
Hence, the next three terms of given G.P series are
42 hours
EXPLANATION:
To find the answer, we should start with the total and get rid of the amounts that we know.
So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.
1,172 - 500 =672.
Now we have 672 left.
We know that it was all spent on employees.
we know it is $16 for each hour.
672 divided by 16 is 42 total hours.
Hope this helps!
Yes
Angle 1 and angle 4 add up to 180 degrees because they are on the same straight line split into two parts, and a straight line is 180 degrees. Angle 4 and angle 7 are corresponding angles, which means they occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal. Supplementary angles mean that any two angles add up to 180 degrees. Since 4 and 7 are corresponding, 1 and 7 must be supplementary
The full length of one line times the length of the line outside the circle is equal the the other line.
(7+x)*7 = (13 +8) * 8
Simplify:
7x +49 = 21 * 8
7x +49 = 168
Subtract 49 from each side:
7x = 119
Divide both sides by 7:
x = 17
The answer is B. 17
