PSAT Math Multiple-Choice Practice Question 693
Question: 693
In a right triangle with legs of length a and b, what is the value of the hypotenuse of the triangle?
Correct Answer: C
Explanation:
(C) In a right triangle, we can use the Pythagorean theorem to solve for an unknown hypotenuse. a2 + b2 = c2 where a and b are the 2 shorter legs and c is the hypotenuse. To solve for c, you take the square root of both sides:
This matches choice (C).
