Find the hypotenuse of a right triangle given the legs 20 cm and 21 cm.
What is the length of the hypotenuse?
a. 29 cm
b. 22 cm
c. 13 cm
d. 5.8 cm

Answer:

a. 29 cm

Step-by-step explanation:

We can find the length of the hypotenuse using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.

20² + 21² = h²

  • h: hypotenuse, calculate the square values.

400 + 441 = h²

  • Add the numbers.

841 = h²

  • Find the root for both sides.

29 = h
