The neap tide is tide that occur when sun,earth and moon are positioned to form a right triangle in space.The sun,earth and the moon form a right angle and the gravitational pull of the sun counteracts the pull of the moon.This neap tide occurs when the difference between high and low tide is least. In addition the neap tide comes twice a month,in the first and third quarters of the moon.
Below I have included an image that has the measure of all of the angles on it.
We can find the measures of the angles here due to the laws about complimentary angles. A pair of complimentary angles can be formed when 2 lines are perpendicular, and when added together, will always equal 90. The pair are the angles that are not directly adjacent from each other. In this figure, "x" and "(4x-10)" are a pair. According to another law, opposite angles, or adjacent angles, will always be equal to each other. Using the logic above is how we can find the measure of all angles.
Since one angle has a box, we know the lines are perpendicular, and that the laws of complimentary angles apply. We can also use that to see that the angle diagonal from it is equal to 90.
To solve for the other measures, we need to add the 2 equations together and set them equal to 90 (because of that law we talked about before).
x+(4x-10)=90
5x-10=90
+10+10
5x=100
/5 /5
x=20
Now that we know x equals 20, we can substitute that value in and solve.
x=20
=(4x-10)
=(4*20-10)
=(80-10)
=70
We also know this is correct because 20 and 70 equal 90.
High lattitudes is the answer
China has become a world leader in production of farm products including rice, wheat, potatoes, sorghum, peanuts, tea millet, barley, cotton, oilseed and soybeans. Initially going back eons, first the use of cast iron tools and beasts of burden were introduced in agriculture. Now, while communes have beendisbanded, and individual farming has been restored, there are quotas for the individual farmers and also some state farms. In modern times, mechanization has been promoted and state sponsored projects like the Three Gorges Dam has provided significant irrigation.
