    Answer:

    25

    Step-by-step explanation:

    To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:

    15^2 + 20^2 = c^2

    225 + 400 = c^2

    625 = c^2

    c = 25

    This means the hypotenuse is 25.

    A2 + B2 = C2 is the Pythagorean Theorem where A and B are the legs and C is the hypotenuse.

    (15cm)2 + (20cm)2 = C2 after substitution

    225cm2 + 400cm2 = C2 add

    625cm2 = C2 Take square root of both sides

    25cm = C which is the hypotenuse.
