1. Hello, miner
2. The process of BTC address generation is as follows. You can check bitcoin Chinese wiki completely:
bitcoin address generation process
(Note: some numbers are marked with & quot; 0x" Begin with, meaning that the number is in hexadecimal notation& quot; 0x" It doesn't have any meaning in itself. It's a conventional writing method handed down from C language. For example, 0xa is 10 in decimal system. In addition, 1 byte = 8-bit binary = 2-bit hexadecimal)
in the first step, randomly select a 32 byte number and size from 1 to 0xFFFF ffff ffff ffff ffff ffff ffff fffe baae dce6 af48 a03b BFD2 5e8c d036 4141 as the private key
in the second step, the elliptic curve encryption algorithm (ecdsa-secp256k1) is used to calculate the uncompressed public key corresponding to the private key A total of 65 bytes, 1 byte is 0x04, 32 bytes are x coordinates, and 32 bytes are y coordinates
the third step is to calculate the SHA-256 hash value of the public key
the fourth step is to take the previous step result and calculate the ripemd-160 hash value
the fifth step is to take the previous step result and add the address version number (bitcoin main network version number "0x00")
00
the sixth step is to take the previous step result, Calculate the SHA-256 hash value
Step 7, take the result of the previous step, and then calculate the SHA-256 hash value (HA HA)
Step 8, take the first four bytes (8-bit hexadecimal)
d61967f6
Step 9 of the result of the previous step, and add these four bytes after the result of step 5, As a check (this is the hexadecimal form of the bitcoin address)
00d61967f6
Step 10: change the address with base58 notation (this is the most common form of bitcoin address)< br />

3. ∵∠B=24°，∠ACD=56°，
∴∠BAC=32°，
∵AE平分∠BAC，
∴∠BAE=16°，
∴∠AED=∠B+∠BAE=40°．
故选：D．
∴∠BAC=32°，
∵AE平分∠BAC，
∴∠BAE=16°，
∴∠AED=∠B+∠BAE=40°．
故选：D．
4. In other words, I didn't see the figure
because the angle ADB = 90, the angle abd = 36
so the angle bad = 54
and because the angle BAE = the angle CAE = 17
so the angle DAE = 54-17 = 37
looks like it

5. ◆表达有误,题中应该是AE平分角BAC.
∵AE平分∠BAC.
∴∠BAE=(1/2)∠A=(1/2)(180°-∠B-∠C)=90°-(1/2)∠B-(1/2)∠C.
∵FD垂直BC.
∴∠F=90°-∠FED=90°-(∠B+∠BAE)=90°-[∠B+90°-(1/2)∠B-(1/2)∠C]
即∠F=(1/2)(∠C-∠B).
∵AE平分∠BAC.
∴∠BAE=(1/2)∠A=(1/2)(180°-∠B-∠C)=90°-(1/2)∠B-(1/2)∠C.
∵FD垂直BC.
∴∠F=90°-∠FED=90°-(∠B+∠BAE)=90°-[∠B+90°-(1/2)∠B-(1/2)∠C]
即∠F=(1/2)(∠C-∠B).
6. 因∠DAE=∠BAE-∠BAD ∠BAE=∠BAC×1/2=180°-∠B-∠C/2∠BAD=90° -∠B
所以∠DAE=180°-∠B-∠C/2-(90° -∠B )=(180°-∠B-∠C-180+2∠B)/2=(∠B-∠C)/2
即∠DAE=(∠B-∠C)/2
所以∠DAE=180°-∠B-∠C/2-(90° -∠B )=(180°-∠B-∠C-180+2∠B)/2=(∠B-∠C)/2
即∠DAE=(∠B-∠C)/2
