Given:
∆ABC, right angle at B
AC = 2.5cm
BC = 1.5cm
To Find:
length of AB
Solution:
[Refer the attached file for∆ABC]
In ∆ABC [Pythagoras Theorem]
(AC)² = (AB)² + (BC)²
(2.5)² = (AB)² + (1.5)²
6.25 = (AB)² + 2.25
(AB)² = 2.25 - 6.25
(AB)² = 4.00
AB = √4
AB = 2
Hence, the length of other side is 2cm.
