Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles in a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7, thus
sum = 180° × 5 = 900°
Sum the interior angles and equate to 900
x + 146 + 122 + 142 + 140 + 110 + 142 = 900, that is
x + 802 = 900 ( subtract 802 from both sides )
x = 98
Whenever you see of, it means times. Always multiply :) So .25 times x.

Step-by-step explanation:
To find the probability of selecting a horse in the barn, we need to know the total number of horses and the number in the barn.
To find the total, add the values in the "Total" row:
16 + 11 + 12 + 39 = 78
To find the number of horses in the barn, add the values in the "In the barn" row:
4 + 2 + 7 + 13 = 26
Now divide 26 by 78 to find the probability:
26/78 = 1/3 or about 33%
The answer is 33%
