Question

Select the measurements that match the sides of a triangle.
(a)5, 8, 18
(b)6, 12,3
(c) 9,9,9
(d) 7,5, 2​

Answer 1

Answer:

(c) 9,9,9

Step-by-step explanation:

(a) 5, 8, 18

Here, we have,

=> 5+8 = 13

Thus, we have,

=> 13< 18

=> 5+8 < 18

(b) 6, 12, 3

Here, we have,

=> 6+3 = 9

Thus, we have,

=> 9 < 12

=> 6+3 < 12

(c) 9, 9, 9

Here, we have,

=> 9+9 = 18

Thus, We have

=> 18 > 9

=> 9+9 > 9

(d) 7, 5, 2

Here, we have,

=> 5+2 = 7

Thus, we have,

=> 7 = 7

=> 5+2 = 7

Now, we know that, for three lengths to be the sides of a triangle, the sum of two sides must be greater than the third side.

So, according to this, only the option (c) satisfies our required condition.

Hence, correct answer is (c) 9,9,9.
