A pole that is 3.2m tall casts a shadow that is 1.29m long. At the same time, a nearby tower casts a shadow that is 39.25m long.

pashok25 [27]

Set up a ratio of height over shadow length:

3.2/1.29 = X/39.25

Cross multiply:

1.29x = 3.2 * 39.25

Simplify:

1.29x = 125.6

Divide both sides by 1.29:

x = 97.364 meters

Round to the nearest meter = 97 meters

8-the formula to find an exterior angle of a polygon is:
360/n
(n is the number of sides of the polygon)

so the answer is 40
$\frac{360}{9} = 40$

9 - the formula to find an interior angle of polygon is:
$\frac{(n - 2) \times 180}{n}$
so the answer is 135
$\frac{(8 - 2) \times 180}{8} = \frac{6 \times 180}{8} = \frac{1080}{8} = 135$

good luck
