Question

Triangle ABC is right angled at C. If AB=25 and AC=7cm find BC​

Answer 1

Answer:

To find any side of a Right angle triangle, we can use Pythagoras Theorem that is -

(H)² = (P)² + (B)²

(AB)² = (AC)² + (BC)²

Now let's put the values,

(25)² = (7)² + (BC)²

625 = 49 + (BC)²

625 - 49 = (BC)²

576 = (BC)²

√576 = BC

24 = BC

So.... BC = 24 Ans
