B. Encouraging a decrease in overconsumption
C. Building a much stronger economy
D. Using technologies that can harvest resources faster
Answer: B. Encouraging a decrease in overconsumption.
Explanation:
Sustainability can be define as the judicious use of the resources. This suggests that the use of the resources should be in a way so that they can meet the needs of the present as well as the future human population.
Among the options given, B. Encouraging a decrease in overconsumption. is the correct option. This is because of the fact that if the resources are overconsumed this will lead to the scarcity of the resources. This will not help in maintaining the sustainability of resources in the population.
B. 40°
C. 80°
D. 100°
B. 40°
m∠BAC = 40°
But, angles in a triangle adds up to 180 degrees, therefore;
m∠BAC = 180 - (m∠ACB + m∠ABC)
= 180 - (50 + 90)
= 180 - 140
= 40°
Thus; m∠BAC = 40°
The solution of m∠BAC is mathematically given as
m∠BAC = 40°. This is further explained below.
The angle formed by two crossing lines or surfaces, commonly expressed as a number of degrees.
Generally, the equation for angle m∠BAC is mathematically given as
m∠BAC = 180 - (m∠ACB + m∠ABC)
m∠BAC = 180 - (50 + 90)
m∠BAC = 40°
In conclusion, m∠BAC = 40°
