Sin and cosine of the acute angle are complementary trigonometric functions. This means that between these trigonometric functions, the rule of complementary acute angles applies: sin64° = cos(90°-64°) = cos26°
So, if we have given cos64° = cosx and we want to determine the value of the acute angle x, given the complementarity of the angles to 90 degrees, the required value of the angle x is 26°.
The answer is: x = 26°
The three physical changes that happen to teen brains that make it difficult for someone like Gary to weigh risk and reward include:
- Remodeling of the brain
- Peak sensitivity to the neurotransmitter dopamine
- Influence of the steroidal hormones
<h3>What three physical changes occur in teen brains affect their ability to weigh risk and reward?</h3>
The brain is the most complex organ in the body which controls the functions of other bodily systems, organs, and processes such as thought, emotion, vision, breathing, movement, hunger and every other regulatory functions in the body.
During the teen years, the brain undergoes remarkable physical changes which affect the thought processes of the teenager in weighing risk and reward, such that the teen seeks more reward over risks.
These changes include:
- Remodeling of the brain in a back-to-front manner such the teen relies more on the back part of the brain, the amygdala, which is associated with strong emotions, aggression, and impulsive behavior for decision-making rather than the prefrontal cortex, which is associated with rational decision-making.
- Peak sensitivity to the neurotransmitter dopamine, which is linked to the reward system of the brain.
- Influence of the steroidal hormones produced during puberty.
In conclusion, a teenager like Gary will find it difficult to make rational decisions always because of these changes that occur in the brain during the teen years.

The statement 'a norm is a set of expected behaviors for a particular position' is False.
<h3>What is a norm?</h3>
A norm is a specific value and/or ideal adopted by society as true and established in its culture and costumes.
Norms are fundamental for the healthy functioning of a society and allows to establish parameters of development.
The true statement here is 'a ROLE is a set of expected behaviors for a particular position'.
In conclusion, the statement 'a norm is a set of expected behaviors for a particular position' is False.
