One side of a triangle is 9 feet shorter than the second side. the third side is 2 feet longer than the second side. the perimeter of a triangle is 38 feet. find the length of each side.

First side - 6

Second side - 15

Third side - 17

Step-by-step explanation:

The triangle has three sides and when added together they equal 38.

So if the second side is x, then the other sides are x-9 and x+2.

So x+x - 9 +x+2 = 38.

3x-7 = 38

3x = 45

x=15 so the second side is 15.

So the first side is x-9 = 15-9 = 6

The third side is x+2 = 15+2=17

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
