Two sides of an obtuse triangle measure 10 inches and 15 inches. the length of longest side is unknown.
what is the smallest possible whole-number length of the unknown side?

The smallest possible whole-number length of the unknown side is

Step-by-step explanation:

we know that

The triangle inequality theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x-----> the length of longest side

Applying the triangle inequality theorem

case A)

Rewrite

case B)

The solution of the third side is the interval------->

but remember that

In an obtuse triangle

Round to a whole number

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
