Atriangular sign in a store has a perimeter of 5.5'. to of the sides of the triangle are the same length while a 3rd side is 1' longer than those sites. find out lengths of the sides of the sign

So the perimeter is equal to the sum of all the sides.

Let's call X the length of side one and side 2, and side 3 is equal to x+1.

So,

P= S1+ S2 +S3

5.5 = X + X+ (X+1)

5.5 = 3x+1

4.5 = 3x

1.5 = x

So, the sides' lengths are 1.5, 1.5, and 2.5

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
