Question

A triangle has side lengths of 7 and 14.

Select all of the possible lengths for the third side.

7
12
14
17

Answer 1

A^2 + B^2 = C^2

7^2 + B^2 = 14^2

49 + B^2 = 196

196-49=147

Then radical 147

Then your answer will be 12.12

Then round the answer to the nearest whole number

Your answer: 12

Answer 2

12

14

17

Explanation:

The rule with the sides of a triangle is whenever two sides add up it has to be greater than the third side.

For example: 17+7 = 24 , 24 >14, AND 14+17 = 31, 31<7 so 17 is a possible side for the triangle.
