Sin (105) = sin (15+90)= cos 15- ℎ ℎ

Explanation:
sin(105) = sin (60+45) because sin (a +b)= sin a • cos b+ cos a• sin b

Therefore,

sin 105= sin (60+45) = sin 60• cos 45 + cos 60 • sin 45 =

The picture below is your answer.

zysi [14]

Answer:

Explanation:

This phenomenon best illustrates why intelligence tests need to be revised for predictive validity. The tests are taken initially and show high scores, then they are taken again and show even higher scores. This shows that the individuals are getting smarter. If the test continues to be taken without revision then the same results will continue since the individuals will continue to become smarter but the test will continue being the same. Therefore, becoming much easier for the participants every time. This ultimately leads to better and better scores.
