Answer:
∡x = 20°
∡y = 160°
∠z = 160°
Step-by-step explanation:
Angles on a straight line sum to 180°
⇒ ∠z + 20° = 180°
⇒ ∠z = 180° - 20°
⇒ ∠z = 160°
The central angle measure equals the corresponding arc measure.
⇒ ∡x = 20°
⇒ ∡y = ∠z = 160°
pi r squared, it doesnt let me type out the symbols sorry
15 posts plus 2 corner posts = 17 posts. With 17 posts there would be 16 spaces each side.
The space between each is 8 1/8 feet.
The length of one side is the number of spaces multiplied by the distance between each space.
Total length of one side = 16 spaces x 8 1/8 feet = 130 feet
Area = length x width.
It’s a square shape so area = 130 x 130 = 16,900 square feet
Perimeter is the distance around the square, this would be the length of one side x the number of sides.
Perimeter = 130 x 4 = 520 feet
Answer:
The example is telling you to first add up each number then divide by the amount of numbers that are present in the set. There are four in this example.
Secondly the difference between each data point will differ from each number. Basically subtract the sum from each number. Which is 5 in this case. But if its negative flip it to a positive.
Then add up each absolute value and divide by 4 twice.
