1 section is 640 acres.
(1/8)·(1/2)·(1/8)·(640 acres) = 5 acres
_____
The property description actually seems a bit bogus. While 1/128 of 1 section is 5 acres, it is not clear exactly which 1/128 of the section is being specified. This appears to be a math problem, rather than a surveying problem.
Usually quarter-sections are further divided into quarters. Any half piece will be specified according to a cardinal direciton (N, E, S, W), and any quarter piece will be specified using two cardinal directions (NE, SE, SW, NW). An eighth piece would need three directions for its specification, but would typically be described in terms of a half of a quarter (N half of NE quarter, for example), rather than one-eighth.

Answer:
x = 12
Step-by-step explanation:
Segment lengths of each chord have the same product.
(x -2)(x +6) = 9×20
x² +4x -12 = 180
x² +4x +4 = 196 . . . . . add 16 (complete the square)
(x +2)² = 14²
x +2 = 14 . . . . . . . . . . . positive root is the only one useful
x = 12
Answer:
2.4
Step-by-step explanation:
To find the mean absolute deviation, find how much each value is away from the mean, and divide it by the number of numbers you have. In this case, the mean is 5, and the deviation of each number is 4, 2, 0, 2, and 4. Add these up and you get 12. Divide 12 by the number of numbers which you have, which is 5, to get 2.4.
Answer:
70°
Step-by-step explanation:
The total angle in a triangle is 180°. The total angle in a straight line is 180°. From the image attached, the ∠DCA must be greater than 45° because ∠BCA is greater than 90°. This means that ∠DCA is not 36° or 38° or 40° but it is 70°.
Therefore ∠DCA = 70°.
∠BCA + ∠DCA = 180° (angle on a straight line)
∠BCA = 180 - ∠DCA = 180 - 70 = 110°
∠BCA + ∠BAC + 40 = 180° (angle in a triangle)
∠BAC = 180 - 110 - 40 = 30°
