In logic, a condition that must be satisfied for a statement to be true, but does not in and of itself make it true. Sufficient
Archy [21]

Answer:

Correlation

Step-by-step explanation:

  • This can be explained if we consider the case of correlation as in correlation this condition can arrive where a statement should be satisfied to be true when does not in or make it true itself.
  • Correlation is indicative of the degree to which there is a fluctuation in one more varying values together. The increase or decrease in the value is indicated by the positivity or negativity of the correlation respectively where the correlation itself does not make it true or is true in itself.
  • sufficient and necessary conditions are fulfilled only when one value needs to be true or false for the other to be true or false respectively.
  • Causality also known as causation is  the effectiveness or potency in which one process or a cause, leads to the generation of of another process or an effect, where cause and effect are partially dependent on each other.

To measure a stone face carved on the side of a​ mountain, two sightings 750 feet from the base of the mountain are taken. if th
Sergeeva-Olga [200]

Answer: 57.8512 feet (approx)

Step-by-step explanation:

Let h be the height of the stone face.

The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°

⇒ The distance of the base of the stone face from the base of the mountain = 750\times tan 33^{\circ}=750\times 0.64940759319=487.055694898

The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,

Therefore,

The distance of the top of the stone face from the base of the mountain  = (h + 487.055694898) feet

By the trigonometry,

\frac{h + 487.055694898}{750}=tan36^{\circ}

h + 487.055694898=0.726542528\times 750

h =544.906896004-487.055694898=57.8512011059\approx 57.8512

Therefore, the height of the stone face is 57.8512 feet (approx).
