A right triangle has legs of 6 and 8 units. How long is the hypotenuse?

Answer and explanation

Correct answer: C. 10

  1. Step 1: c squared = 6 squared + 8 squared = 100. Step 2. c = 10. Answer: 10. Why not the others: 14: this adds the legs instead of using the Pythagorean theorem. 100: this is the square of the hypotenuse; the square root was not taken. 2: this subtracts the legs.
