Aregular decagon has a perimeter of 350 ft. what is the length of each side?

Alright, lets get started.

A regular decagon has 10 equal sides.

The perimeter of a regular decagon will be = 10 a

where a is the length of the side

So,

Dividing both sides with 10

a = 35 feet

Hence the length of the side is 35 feet. : Answer

Hope it will help :)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
