how many different triangles can you make if you are
given these two lengths for sides?
25 in.
18 in.
(infinitely many)
0.
1
2
or 3

Answers

the missing   length should be any number from 8 to 32 (8,9,

25-18=7

18+25=33

bigger than 7(not equal to 7)

smaller than 33(not equal to 33)

infinitely many

Step-by-step explanation:

Infinitely many triangles.

Step-by-step explanation:

Given the lengths of two sides are 8 inches and 10 inches.

Let's assume third side = x inches.

Using the Triangle Inequalities given as follows:-

1. a+b > c,

2. b+c > a,

3. c+a > b.

Using the lengths given in the problem, we can write:-

1. x+8 > 10 ⇔ x > 10-8 ⇔ x > 2.

2. x+10 > 8 ⇔ x > 8-10 ⇔ x > -2.

3. 8+10 > x ⇔ x < 18.

So, the solution set is 2 < x < 18. It means third side can take any value in interval (2, 18).

Hence, there are infinitely many triangles.
