Triangle GHI

is a right triangle. The length of one leg is 11 and the hypotenuse is 22. What is the length of the other leg? Round your answer to two decimal places.(1 point)

1 answer

To find the length of the other leg of the right triangle GHI, we can use the Pythagorean theorem, which states:

\[ a^2 + b^2 = c^2 \]

where \( c \) is the length of the hypotenuse, and \( a \) and \( b \) are the lengths of the legs. In this case:

  • Let \( a = 11 \) (one leg)
  • Let \( b \) be the unknown leg length
  • Let \( c = 22 \) (the hypotenuse)

Substituting the values into the equation gives us:

\[ 11^2 + b^2 = 22^2 \]

Calculating the squares:

\[ 121 + b^2 = 484 \]

Now, subtract 121 from both sides:

\[ b^2 = 484 - 121 \] \[ b^2 = 363 \]

Next, take the square root of both sides to find \( b \):

\[ b = \sqrt{363} \]

Calculating the square root:

\[ b \approx 19.08 \]

Thus, the length of the other leg rounded to two decimal places is:

\[ \boxed{19.08} \]
