x = A 21.6 B 12.9 C 9.1

Answers

Hi there! Use the equation below.

[tex] \large{sin57 \degree = \frac{10.8}{x} }[/tex]

The reason why we use this equation because we know that sinA = opposite/hypotenuse. Here we focus on 57°. Our opposite would be 10.8 and hypotenuse is x. Hence sin57° = 10.8/x

You might need a calculator or a trigonometric table to find the value of sin57°. Note that not all values are exact. They are approximate.

Therefore, sin57° ≈ 0.838.

Rewrite the equation.

[tex] \large{0.838 = \frac{10.8}{x} }[/tex]

Solve the equation for x-term.

[tex] \large{0.838(x) = \frac{10.8}{x} (x)} \\ \large{0.838x = 10.8} \\ \large{x = \frac{10.8}{0.838} } \\ \large{x = 12.88}[/tex]

Then round up to the nearest tenth. Hence, the value of x is 12.9

Answer

x ≈ 12.9

B.Larger plants and animals inhabit the area.
C.Biodiversity decreases.
D.Sustainability increases.

Answers

Answer:

uhh C?

I think

Biodiversity decreases does NOT occur as ecological succession progresses. Hence, option C is correct.

What is ecological succession?

The process by which a region's species and habitat mix evolves over time is called ecological succession. These communities gradually replace one another until a "climax community" is attained, such as a mature forest, or until a disruption, such as a fire, happens. A key idea in ecology is ecological succession.

For instance, when a tree falls in an established forest, sunlight may once more be able to penetrate the forest floor, allowing new growth to start. In this instance, fresh, smaller plants would be the first in the succession. Communities are ever-evolving and expanding.

ecological succession is the process by which a biological community's structure changes over time. Primary and secondary succession have been identified as two distinct forms.

Thus, option C is correct.
