Question

प्रश्न 5 दिए गए AABC में भुजा BC की लंबाई ज्ञात कीजिए । C C 12cm B A 36cm​

Answer 1

Given : ΔABC  

AB = 36 cm

AC= 12 cm

To Find : BC की लंबाई

Solution:

Using Pythagorean theorem

BC² = AB²  + AC²

AB = 36 cm

AC = 12 cm

BC² = 36² + 12²

=> BC² = 12² * 3²  + 12²

=> BC² = 12²(9 + 1)

=> BC² = 12²(10)

=> BC = 12√10 cm

=> BC ≈ 37.947 cm
