In a right-angled triangle ABC, if angle B = 90°, BC = 3 cm and AC = 5 cm, then the length of side AB is

Given: angle B = 90°, BC = 3 cm and AC = 5 cm

Formula Used/Theory:-

Pythagoras theorem:-

Base² + Height² = Hypotenuse²

3cm² + Height² = 5²

9 + Height² = 25

Height² = 25 – 9 = 16

Height = √16 = 4cm

∴ AB = 4cm

The measures of ∠x and ∠y in Fig. 6.14 are respectively

If length of two sides of a triangle are 6 cm and 10 cm, then the length of the third side can be
