Answer:
D) 15
Step-by-step explanation:
The sum of the interior angles of a polygon is given by
[tex](n - 2) \times 180[/tex]
We have that, the sum of the interior angles of a polygon is
26 right angles. We want to find n, the number of sides.
We substitute into the formula to get:
[tex](n - 2) \times 180 = 26 \times 90[/tex]
Divide through by 90
[tex]2(n - 2) = 26[/tex]
Divide through by 2
[tex]n - 2 = 13[/tex]
[tex]n = 13 + 2[/tex]
[tex]n = 15[/tex]
