May someone help thank you so much

<A=135°

now

3x+6+x+2=180

sum of two opposite angle of the cyclic quadrilateral is 180

4x=180-8

x=172/4=43°

<A=3×43+6=135° is your answer

2345, 2034, 2134

Step-by-step explanation:

We know that the first digit out of the four-digit PIN must be between 1 to 9. Also, other three digits must be any combination of 0 to 9 with no repetition.

Now according to options:

A. 0123, 0456, 0789: the first digit is 0, which is not possible.

B. 1012,1033,1004: there is repetition in the last three digits of the 4-digit PIN, which is again not possible.

D. 3200, 4200, 5200: same as option B there is a repetition in the digits, which is not possible.

Hence, option C. 2345, 2034, 2134 is correct.
