The sum of the interior angles of a polygon is given by
180(n-2)
Where n is the number of sides of the polygon.
Sum = 180(14 - 2)
= 2160°
The answer is C

Answer: (-4,-2)
Step-by-step explanation:
Looking at the graph, if you move from the zoo downwards for 7 units, you will arrive at point B which is also 2 units from the park.
Point B is therefore the doctor's office and its coordinates are, (-4, -2)
Answer:the number of BlackBerry that Arlene had initially was 276
Step-by-step explanation:
Let x represent the number of BlackBerry that Arlene had initially.
She gave 216 to her teachers. This means that she is left with x - 216
Then she dropped 12. This means that she would be left with x - 216 - 12 = x - 228
Later, she ate 18. This means that she would be left with x - 228 - 18 = x - 246
Finally, she gave half of what she had to her friend. This means that the amount that she gave to her friend is (x - 246)/2 and the amount that she has left would be
(x - 246)/2
Now, she has 15. This means that
(x - 246)/2 = 15
x - 246 = 2 × 15 = 30
x = 30 + 246 = 276
It is 17 bc the 18 times 34
