Which term refers to the variety of observable and unobservable similarities and differences among people?

Diversity

Step-by-step explanation:

Diversity is a biological term which helps to show the different changes or variations both those observed or those not observed that exists within a sample or a population. Diversity can occur as a result of Genetic different in the genetic makeup of the individuals involved.

Their are no exactly the same kind of persons in the world as one or more forms of difference must exist either in PHENOTYPE OR GENOTYPE OF PEOPLE.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
