What is the length of EF in the right triangle below? E 17 13 F A. 458
B. 458
C. 4
D. 1120
E. 30
F. 120

The answer is D. √120

Step-by-step explanation:

Using the pythangorean theorem when solving the missing side of a right triangle, so given a^2 + b^2 = c^2. We have side c, and a so we must rearanged this to fit side b.

So: a^2 + b^2 = c^2 → b^2 = c^2 - a^2 →

b = √(c^2 - a^2).

Given side c or the hypotenuse is 17, and a is 13. side b must have a length of:

√(17^2-13^2) = √(289 - 169) = √120
