Dream of opening mountains and building roads

Dream of cutting down mountains and building roads "Xuanyuan Dream Book"

Dreaming is a normal psychological phenomenon during sleep. Under normal circumstances, human brain nerve cells are in a state of inhibition during sleep, and this inhibition process is sometimes complete and sometimes incomplete.

If it is not completely suppressed,

There are still a few nerve cells in the cerebral cortex in an excited state, and people will dream.

Dreaming of cutting mountains, building roads and diverting water, whether in dreams or in reality, is a just move to benefit the people, which shows that you are very talented and may not have met Bole yet. Please adopt it.

Dreaming of meeting a woman on the mountain stone road _ Duke Zhou's inquiry _ Buddhist fortune-telling network dreaming of meeting a woman on the mountain stone road-dream:

Good or bad luck index: 85 (from Buddhist mathematical culture, for reference only)

I dreamed of building roads with stones and meeting women: being single has a good chance to participate in group activities. The number of men and women is equal, and mixed party activities have the best omen. If you don't have such activity information, don't forget to ask your friends first. If you are new boyfriend and girlfriend, then this date can speed up the distance between you. It is also a good time for couples to date, so arrange a sweet date for yourself.

I dreamed that I was trapped on a mountain road in a trailer and was magically released. If a person is awakened directly from REM sleep (for example, by an alarm clock), he is likely to report to you that he is having a vivid dream.

Why do you burn paper? No matter what you do, whether you cut the ribbon or lay the foundation, it is actually a kind of project.

And secretly burning paper is also for safe production.

Can the ancients build mountains and roads? Yes

The most famous is that Gong Yu moved mountains.

Other blessing allusions include the secret crossing of Chencang by building plank roads in Ming Dynasty; There are practical examples of cutting mountains and building roads in Yunnan, Sichuan, Chongqing and other places.

As shown in the figure, 10, a mountain was opened and a road was built along the alternating direction. It is known that DF = BD and DM = DE, so the quadrilateral BMFE is rectangular, so MFBE, ABMF, B and B are on AC, so A, C and E are on a straight line.

In a road reconstruction project, it is necessary to cut mountains and build roads along the AC direction (pictured). In order to speed up the construction progress, construction must be carried out on the other side of the mountain at the same time. AC's answer is really funny. The right angle of Germany is 642.8 meters, which is longer than the hypotenuse of 520 meters. . . Do you want to verify it when it's finished? Carelessness in junior high school is a habit, not to mention high school. Isn't the university a heavenly book!

First, write clearly. If you want to be in a straight line, make a vertical line to connect DE vertically to AC. Angle DBE=40 degrees, angle BDE=50 degrees, angle AED should be equal to 180-40-50 = 90 degrees, which meets the requirements. This is just verification, but still write. . .

De/520 = sin40 = cos50, which can be calculated as 334m.

In fact, this problem assumes that point D is in the middle of the mountain, which can also be done, so it is necessary to check that the sum of the three angles is 180. In real life, we need to measure two angles to verify the third angle.
