    yes a right triangle

    Step-by-step explanation:

    Using the converse of Pythagoras' identity

    If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right,

    53² = 2809 ← square of longest side

    28² + 45² = 784 + 2025 = 2809

    Thus the triangle is right
