Answer 2

$\bold{ \underline{In \: Δ \: ABC \: , \: </p><p> \: \: }}$

$\to$ AB = 10 units

$\to$ BC = 6 units

By Pythagoras theorem ,

$\to$ AC² = AB² - BC²

$\to$ AC² = ( 10 )² - ( 6 )²

$\to$ AC² = 100 - 36

$\to$ AC² = 64

$\to$ AC = √64

$\to$ AC = 8

$\underline{ \bold{In \: Δ \: ACD \: , \: }}$

$\to$ CD = x units

$\to$ AD = 17 units

$\to$ AC = 8 units

By pythagoras theorem ,

$\to$ CD² = AD² - AC²

$\to$ CD² = 17² - 8²

$\to$ CD² = 289 - 64

$\to$ CD² = 225

$\to$ CD = 15

Hence , the value of x is 15 units
