The central angle COA = 2 * angle at the circumference
m < COA = 2 * 80 degrees
You subtract c^9 - c^14 and you get c^5
then you subtract d^-7 - d^-10 and you get d^3 because negative and a negative make a positive.
so your answer is:
d^3/c^5
Yes. When a graph has more than one line it is a piece wise graph.
Answer:
- 1/5
Step-by-step explanation:
Slope of a line passing through two points can be calculated as:

The given points are (-2, -1) and (8, -3). Using the values in above formula, we get:

Thus the slope of the line through the given points is -1/5. So 2nd option gives the correct answer
Answer:
Step-by-step explanation:
<u>27.</u> the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 <u>x=9 </u>
<u>28. </u> the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
<u>x=120</u>
