Answer:
11.2 units
Step-by-step explanation:
From (-7, -7) to (-2, 3) is 5 units horizontally and 10 units vertically. Thus we have a right triangle with sides 5 and 10 respectively. The length of the hypotenuse of this triangle is the distance between (-2, 3) & (-7, -7):
d = √(5² + 10²) = √(25 + 100) = √125 = √25√5, or 5√5.
This is approximately 11.2 units
Answer: To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem.
Step-by-step explanation:
10 to the exponent 2 is equal to 100, so 8.7 x 100 is equal to 870
Answer:
28° is the missing angle :p

The lines stand for absolute value. The expression would then look like:
13+26-18+12
39-18+12
21+12
