Find an angle between 0 and 2 that is coterminal with the given angle.

Express sin A,cos A and tan A as ratios

OverLord2011 [107]

Answer:

Part A) $sin(A)=\frac{2\sqrt{42}}{23}$

Part B) $cos(A)=\frac{19}{23}$

Part C) $tan(A)=\frac{2\sqrt{42}}{19}$

Step-by-step explanation:

Part A) we know that

In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse

so

$sin(A)=\frac{BC}{AB}$

substitute the values

$sin(A)=\frac{2\sqrt{42}}{23}$

Part B) we know that

In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse

so

$cos(A)=\frac{AC}{AB}$

substitute the values

$cos(A)=\frac{19}{23}$

Part C) we know that

In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

so

$tan(A)=\frac{BC}{AC}$

substitute the values

$tan(A)=\frac{2\sqrt{42}}{19}$

A Thurstone scale was constructed to measure creativity. The scale scores ranged from 1 to 13. If the scale was properly constru

Sonja [21]

Answer: A person with a score of 6 was more creative than a person with a score of 5

Step-by-step explanation: The Thurstone scale is usually employed in the representation of non-numerical attributes such as creativity, like or dislike, understanding and so on. in a numerical format usually in questionnaires or surveys in other to denote the level of agreement or disagreement with the statement or create ranking. However, despite being represented in numerical format to create distinction and processing. Variables measured cannot be subjected to mathematical calculation.

In the scenario above, creativity is represented in numerical format to show the level of creativity such that individuals with higher numbers are deemed more creative than those with lesser figures. However, it is wrong to Infer that an individual with creativity score of 6 is twice as creative as those with a creativity of 3.

IT just shows that individuals with 6 are more creativity than those with 5 and so on.
