Answer:
539
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
Where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 17 - 8 = 26 - 17 = 9, thus
= 8 + (9 × 59) = 8 + 531 = 539

Answer is 12.73
Use Pythagorean theory
Split square into two right triangles with diagonal line. To find the diagonal
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
162= c^2
Take square root of both sides
12.73 = c
