Question

in abc,m b=90⁰ and l( bc) =3 cm l(ac) = 5cm find AB ?​

Answer 1

Step-by-step explanation:

in right angle triangle, triangle ABC angle B=90°and segment AC is the hypotenuse.

therefore by Pythagoras theorem

[l(AC)]²=[l(BC)]²+[l(AB)]²

(5)² =(3)²+x²

25 =9+x²

25-9

16

(4)²

therefore l(AB)=4 cm

answer=the length of the segment is AB is 4cm
