Metamorphism is the addition of heat and/or pressure to existing rocks, which causes them to change physically and/or chemically so that they become a new rock. Metamorphic rocks may change so much that they may not resemble the original rock.
The region that was hit the hardest by the bubonic plague in the 1300's was the Mediterranean region.
Big portions of Europe had big losses when this disease came to the European soil, but the Mediterranean region, on European, Asian, and African soil, was hit the hardest and had the biggest losses in human lives. The body didn't had a defense system for this disease nor do the medics of the period had a solution for it, so once someone got it, it meant that the person is destined to die in a matter of days.
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>
