What is the length of the missing leg? If necessary, round to the nearest tenth. a=58 c=48 b=?

can u find the length of b?

1 answer

To find the length of the missing leg \( b \) in a right triangle where \( a \) and \( c \) are known, we can use the Pythagorean theorem:

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

where

  • \( c \) is the length of the hypotenuse,
  • \( a \) and \( b \) are the lengths of the two legs.

Given:

  • \( a = 58 \)
  • \( c = 48 \)

First, substitute the values into the Pythagorean theorem:

\[ 48^2 = 58^2 + b^2 \]

Calculating \( 48^2 \) and \( 58^2 \):

\[ 48^2 = 2304 \] \[ 58^2 = 3364 \]

Now, substitute these values into the equation:

\[ 2304 = 3364 + b^2 \]

Now, solve for \( b^2 \):

\[ b^2 = 2304 - 3364 \] \[ b^2 = -1060 \]

Since \( b^2 \) is negative, it indicates that a triangle cannot exist with these side lengths (specifically \( a \) cannot be larger than \( c \) for a right triangle).

Since \( a \) must be shorter than \( c \) in a right triangle, please double-check the assigned values of \( a \) and \( c \). If \( c \) is indeed the hypotenuse, then we need \( a \) to be shorter than \( c \).

If there's an error in the values provided, please correct it, and I can help you find the correct length of \( b \).
