Answer:
a = 3
Step-by-step explanation:
The x-values 5, 3, 1 form an arithmetic sequence. The y-values will do the same: 1, 2, a = 1, 2, 3 -- a common difference of +1.
a = 3
6561^1/2 (^1/2 means to the power of a half, which is the same as the square root)
9^2
3^4
A^2 + b^2 = c^2
base lines: home to first is a, first to second is b, home to second is c.
90^2 + 90^2 = c^2
or
...approximately
The simplified expression is 6+3i
