A triangle has side lengths of 9 centimeters and 15 centimeters. The third side has a length of x centimeters. complete the inequality to show all the possible values of x.

Sagot :

Answer:

67.5

Step-by-step explanation:

area of a triangle (1/2 l×b)

1/2 ×9×15× x=135x

divide any side by 2

x=4.5×15=67.5

x=67.5

The value of x is 67.5.

We have given that,

A triangle has side lengths of 9 centimeters and 15 centimeters.

The third side has a length of x centimeters

What is the area of a triangle?

The area of a triangle is  (1/2 l×b)

l is length and b is a breadth.

Therefore we use the given value in the formula so

1/2 ×9×15× x=135x

divide any side by 2

x=4.5×15=67.5

x=67.5.

Therefore the third side of the triangle is 67.5.

So the inequality is

67.5≤15≤9.
