Answer:

25

Step-by-step explanation:

To obtain the length of BC, we shall apply the pythagoras theory as show below:

From the diagram above, the pythagoras theory states as follow:

|BD|² = |CD|² + |BC|²

|BD| = 65

|CD| = 60

|BC| = m

|BD|² = |CD|² + |BC|²

65² = 60² + m²

4225 = 3600 + m²

Collect like terms

m² = 4225 – 3600

m² = 625

Take the square root of both side

m = √625

m = 25

|BC| = m = 25

Therefore, the length of BC is 25
