Because of the rapid changing water levels the plant life on the shores are drowning out so they can not grow.
Hope this help. :D
optical telescope (Hubble), X ray telescope ( Chandra) etc.
get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying.
Okay so you can find the angle by working out the angle in the top right corner of the backwards 'Z' shape. Because there's 180 degrees in a straight line, that top right angle is 180 - 132 = 48.
Now we know that the top right angle is 48, so the angle you're looking for is 48, because they're alternate angles.
That means 3x + 9 = 48. You can find x by rearranging.
3x + 9 = 48
3x = 48 - 9
3x = 39
x = 13.
x is equal to 13.
