According to Pythagoras Theorem, in a right angled triangle ABC,
(AB)2 + (BC)2 = (AC)2,
where AB and BC are the the two sides of the triangle and AC is the hypotenuse.
So here,
AB = 4.5cm and
AC = 7.5cm
Therefore,
(4.5)2 + (BC)2 = (7.5)2
(BC)2 = (7.5)2 - (4.5)2
(BC)2 = 56.25 - 20.25
(BC)2 = 36
BC= 6
Hence, the length of its third side is 6cm.
(AB)2 + (BC)2 = (AC)2,
where AB and BC are the the two sides of the triangle and AC is the hypotenuse.
So here,
AB = 4.5cm and
AC = 7.5cm
Therefore,
(4.5)2 + (BC)2 = (7.5)2
(BC)2 = (7.5)2 - (4.5)2
(BC)2 = 56.25 - 20.25
(BC)2 = 36
BC= 6
Hence, the length of its third side is 6cm.
