Question

what is the length of BC in triangle if AB = 10 cm AC = 17 cm and the medium AD=8cm​

Answer 1

Answer:

22.81 cm or $3\sqrt{58}$ is your answer

Step-by-step explanation:

• we have a derive of stewart's formula:

• $AB^2+AC^2=2[AD^2+\frac{BC^2}{4} ]$  

• now by using the above formula:
• $10^2+17^2=2[8^2+\frac{BC^2}{4} ]$
• $BC=\sqrt{522} = 22.81 cm$
