Answer:
2√10 units
Step-by-step explanation:
In ∆ABC, seg CD is the median. [Given]
∴ AC² + BC² = 2CD² + 2 BD²
∴ 72 + 92 = 2CD² + 2 (5)²
∴ 49 + 81 = 2CD² + 2 (25)
∴ 130 = 2 CD² + 50
∴ 2 CD² = 130 – 50
∴ 2 CD² = 80
∴ CD2 = 80/2 = 40
∴ CD = √40 [Taking square root of both sides]
=2√10 units
∴ The length of the median drawn from point C to side AB is 2√10 units
