They are often very rich in nutrients and hold water well because of their volcanic ash content. ... These soils are called Andisols, and they are often very young, and acidic depending on which type of volcano they come from.
Answer: B
Explanation: Because it is great
Answer:
<u>Part A. The name of this property is Triangle Exterior Angle Theorem, that states that an exterior angle of any triangle is equal to the sum of the opposite interior angles.</u>
<u>Part B. m ∠ 4 = 77°</u>
Explanation:
Part A. Let's recall that:
i: The interior angles of any triangle always add up to 180 degrees, therefore in our case:
∠1 + ∠2 + ∠3 = 180°, thus:
∠3 = 180 - ∠1 + ∠2
Replacing with the values we have:
∠3 = 180 - 57 - 20
∠3 = 103°
ii. ∠3 + ∠4 are supplementary angles, because they add up to 180 degrees, in consequence:
∠3 + ∠4 = 180 °
Replacing with the values we have:
∠4 = 180 - ∠3
∠4 = 180 - 103
∠4 = 77 and we can substitute 77 by ∠1 + ∠2, then:
∠4 = ∠1 + ∠2
77 = 57 + 20
<u>The name of this property is Triangle Exterior Angle Theorem, that states that an exterior angle of any triangle is equal to the sum of the opposite interior angles.</u>
<u>Part B. m ∠ 4 = 77°</u>
Answer:
Improvements in medical aid technology and increasing use of computer aided design
Explanation:
- As the world's population is going to hit around 10 billion by t end of this century. All due to the increase of technological advancements around the globe.
- Such as the reduction in mortality rate, increase in fertility rates and improvements in livelihood and productive and healthy lifestyle.
- It is due to transformation in society and the economy that is brought about by the help of technology. Due to innovation and enhancement of technology has created massive waves in the life cycle of man and his surroundings.
- Medical aid is now subsidized and free treatment is now available in third world countries, such as the opening of drug centers and fair system to evaluate the use of medicine and patient diagnostics has improved a lot.
- An example of a test-tube baby for the infertility cases and the use of stem cells to treat cancer like diseases. Countries like China and India which are number one in terms of population growth followed by Indonesia and the USA are growing since the industrial age.
