Answer:

The answer to your question is  c = \sqrt{2593}

Step-by-step explanation:

Data

right triangle

short leg = 17 cm

long leg = 48 cm

hypotenuse = ?

c = hypotenuse

a = short leg = 17 cm

b = long leg = 48 cm

- Substitution

-Simplification

             c² = 289 + 2304

             c² = 2593

-Result

             c = \sqrt{2593}
