Step-by-step explanation:

ACB IS A RIGHT ANGLED TRIANGLE

AB = 25

AC = 7

BC = ?

ΔACB IS A RIGHT ANGLED TRIANGLE

SO,APPLYING PYTHAGOROUS THEOREM

HYP² = B² + ALT²

HERE, HYP = 25CM

B = 7CM

ALT = ?

⇒ HYP² = B² + ALT²

⇒ 25² = 7² + ALT²

⇒ ALT² = 25² - 7²

⇒ ALT² = 625 - 49

⇒ ALT² = √576 = 24CM
