kirill115 [55]

Answer:

One-half b c sine (60 degrees)

One-half a squared sine (60 degrees)

StartFraction a b sine (60 degrees) Over 2 EndFraction

Explanation:

The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides.

From the question, Equilateral triangle refer to a triangle with equal angle and equal sides. The sum of an angle in a triangle = 180°; this implies that each angles have 60°.

∴ the three options that defines the expressions that represent the are of triangle ABC are:

One-half b c sine (60 degrees)  

i.e \frac{1}{2}bcsin60^{0}

One-half a squared sine (60 degrees) ; if the two opposite sides posses the same parameters.

i.e \frac{1}{2}a^{2}sin60^{0}

StartFraction a b sine (60 degrees) Over 2 EndFraction

i.e \frac{absin60^{0}}{2}

Which of the following is not a reason that small societies can maintain stability in the long term better than larger societies
Yakvenalex [24]

Answer: d. None of the above

Sustainable development involves the maintenance of human community with the adequate and judicious use of natural resources so that these resources will be available for future use. Small societies can maintain stability in the long terms by following notion of sustainable development. Smaller societies have a smaller demand for resources. As, lesser the number of individuals lesser will be the demand for resources and these resources will be available for future hence, smaller societies will maintain stability. Smaller societies can be governed by internal controls more effectively than larger societies because members can control the use of resources by creating awareness among themselves and use of resources can be checked upon. Small societies rely more heavily on legislation and military forces because these can ensure that all norms of resource conservation and sustainable development are strictly followed by members of the society.

Therefore, all options are useful for maintaining stability in the society.
