We find the length of AD using the similarity of right triangle property. See image attached.
AD² = BD × CD
AD² = 9 × 36
AD² = 324
AD² = 18²
AD = 18
The length of AD is 18 units
To find this value, simply substitute the number 10 in for x in your equation:


The answer is 98.
Look online and find the answers to the workbook that's what I did and I never failed workbook things
If number is equivalent to x.
