Answer:

D) 15

Step-by-step explanation:

The sum of the interior angles of a polygon is given by

(n - 2) \times 180

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:

(n - 2) \times 180 = 26 \times 90

Divide through by 90

2(n - 2) = 26

Divide through by 2

n - 2 = 13

n = 13 + 2

n = 15

Sam traveled 3/4 of a journey by bus. He jogged 1/2 of the remaining distance and walked the rest of the way. If he walked 800 f
Troyanec [42]
Let x = total distance he covered
3x/4         by bus
1/2 . x/4  =  x/8  by jogging
the remaining distance  =  x/8               by walking
thus      x/8 = 800ft
           x =    8 . 800 = 6400ft
