DBC virtual currency

1. Let DN be perpendicular to AB in N, let cm be perpendicular to DN, and let the extension line of DN intersect with M.
prove that DCM and BDN are congruent triangles, then MD = BN, Mn = DN + AB,
let adn be isosceles right triangle, DN = an,
then Mn = AB
so the area of △ ABC = 4.5 = 1 / 2 * AB ^ 2, ab = 3

3. In the legendary world, 1 yuan is 1 yuan. Yuanbao can be obtained by buying the premium card of legend world.

5. There is no best, only targeted. Heavy strengthening is aimed at large calibre rifles, while Samurai suits and PLA bulletproof vests are large calibre and small calibre, but the effect is not very good. Others say that the sniper's lucky probability is very important. In fact, the gunner's luck is also very important. The so-called lucky is that your bullet has a certain probability to directly ignore the armor and cause direct damage to the enemy. The sniper, needless to say, must have killed him with one shot, while the rifleman means that he has already died before the other party's body armor is broken. If you use the latest PLA body armor and PLA uniform, you may be more defensive. If you use the enhanced explosion-proof suit and the fourth generation body armor, you will be more lucky. In fact, the difference is not too big. I don't know about hiding attributes. In addition, even if you buy a helmet, it is only installed on the head of the Scout. As a sniper, you don't enjoy the protection of the helmet. That is to say, if you are a professional sniper, you might as well buy a hat with attributes. The latest fishing cap adds luck and movement speed, and the previous school Beret adds defense and movement speed.... I hope it can help you

6. Hehe, I can't see your picture, but I still want to tell you that as early as the Qing Dynasty, it was invented to use jade powder to heat and mold jade. Now the jade on the stall is made of jade powder or plastic. It's better to buy jade face-to-face. It's better to find big shops, which have good reputation and are safer. There are too many cheaters on the Internet, There are too many fake jades. If you wear them by yourself, you can buy one at most. The maximum price is 150. Don't spend too much money. Most jadeite or jade are not worth money. Jadeite is stone. Some are expensive and some are cheap. The main thing is to see if anyone likes it and is willing to spend that money. The price is just because it looks good but not good. But everyone's aesthetic values are different, The same stone, you say beautiful, but I may not feel good-looking, understand? But it can't be said that this stone is better and more valuable than that one, right?

7. T you always have seconds, which consume more blue, and the price is the same
in fact, catching ghosts is the most profitable place
if you burn doubles, it's still D5, set a moonlight, change into a dragon female card, you can kill 7 monsters per second in a round
you have the chance to get 80 rings

8. Analysis:

the maximum value of these coins: 5 × 6+2 × 10 = 50 cents

because there are only 5 cents and 2 cents, the value of 1 cent and 3 cents can't be combined,

so the corresponding 50-1 = 49 cents and 50-3 = 47 cents can't be combined, It can be proved that there are four kinds of remainder of any currency divided by 5: 0, 1, 2, 3, 4

when the remainder of the currency divided by 5 is 0, 2, 4 (except 49, 47), it can be directly composed of 5 cents or 2 cents

when the remainder is 1 and the currency value is more than 5 cents, It can be understood that the remainder 5 + 1 = 6, so it can also be formed

when the remainder is 3 and the currency value is greater than 5, it can be understood that the remainder 5 + 3 = 8, so it can also be formed

so 50 - 4 = 46 kinds... Can form 46 different currency values.

I hope the information I found for you will be helpful to you~~

9. Internal and external improvements have been made, some small details and bugs have been optimized, and the quality control is better. At least we haven't seen all kinds of bugs ring the first launch of L3. Proct maturity is still a part that needs to be considered
as for the sound, I think the advantage of the single port of l3pro is greater than that of the balanced port based on the comparative listening feeling of the physical stores. The advantage of L3 series balance port over single port is exaggerated. In fact, the separation is better and the volume is higher (this is especially important. Many people think that the quality is high. In fact, if you turn up the single port volume, the quality is not lost at all). Moreover, the single end voice is closer and more comfortable, and the balance port will pull the voice away. In a word, the style difference between balanced port and single port is greater than the quality difference. One is more instrumental than the other is more vocal. It's absolutely OK to push the earplug at the same price. If you push the earphone big, it's better to optimize the design of lp5 for headwear
