Answer: missing side length = 12.5

Step-by-step explanation:

1. Identify what equation to use

there are 2 side lengths, and no Pythagorean triples present therefore using the Pythagorean theorem a^2+b^2=c^2 would be a good approach

2. plug in numbers

knowing the missing side length is the hypotonus we can plug 6 and 11 for a and b: 6^2+11^2=c^2

3. Solve equation

6^2+11^2=c^2

36+121=c^2

157=c^2

12.52=c | to cancel square (^2) you must square root the number

12.5=c | round
