To determine if the triangle with sides measuring 60, 75, and 45 is a right triangle, we can use the Pythagorean theorem. The theorem states that for a right triangle with sides \( a \), \( b \), and hypotenuse \( c \) (where \( c \) is the longest side), the following equation must hold:

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

Given that the sides are 60, 75, and 45, we identify the longest side \( c \) as 75. Therefore, we check if:

\[ 75^2 = 60^2 + 45^2 \]

Calculating each term:

  • \( 75^2 = 5625 \)
  • \( 60^2 = 3600 \)
  • \( 45^2 = 2025 \)

Now, we add \( 60^2 \) and \( 45^2 \):

\[ 3600 + 2025 = 5625 \]

Since both sides match (\( 5625 = 5625 \)), we conclude that the triangle is a right triangle.

The correct response is:

Yes, because 5,625 equals 5,625.
