Answer:
A)
Explanation:
I found the rest of your question.
A. increased water scarcity B. overfishing C. decreased soil salinity D. deforestation
Overfishing, decreased soil salinity and deforestation are concerns about agricultural production and its effect but the increased water scarcity is not.
Overfishing is considering a fish species from the water and because of that population of fish is lack which is not good.
Soil salinity can stop the plant from growing and also the quality of water.
Deforestation is the removal of forests or trees and it has a big effect on agricultural production.
The atmosphere plays an important role in modulating the precipitation and also in the radiative forcing at the land surface, through the radiative effects of clouds, trace gases including carbon dioxide, water vapour and aerosols. ... Clouds are the prime regulator of the energy exchanges in the atmosphere.
Okay, so you take the length of your hypotenuse (17) and plug it into the pythagorean theorem as C. And then plug the given side (15) into A or B (doesn't matter which). So:
<span><span>a2</span>+<span>152</span>=<span>172</span></span>
<span><span>a2</span>+225=289</span>
Now isolate a^2 by subtracting 225 from both sides of the equation.
<span><span>a2</span>=64</span><span>
Find the square root of both sides to find the missing value.
a = 8</span>
