Answer:
98
Step-by-step explanation:
I think it is 98 because it is even, and it is the second largest 2 digit number.
The largest 2 digit number, 99, isn't divisible by 2 because it is an odd number.
A+C = 180 = A + 74 -> A = 106
B +D = 180 = B +88 -> D = 92
x = 92
The largest number is 345
B.) (0,1)
