Find q. Write your answer as an integer or as a decimal rounded to the nearest tenth.

neonofarm [45]

Answer:

13.9

Step-by-step explanation:

To get the length, or the hypotenuse, you do the equation a^2 + b^2 = c^2

Meaning you multiply those known lengths by themselves, then add them.

169 + 25 = 194

Then you find the square root of 194.

The square root would be 13.9283882772, or when rounded to the nearest tenth, 13.9
