Question

use the information given in adjoining figure to find the length of ad

Answer 1

OA=20-10=10
OD=24
AD^2=(10)^2+(24)^2
=100+576
=676
AD=26

Answer 2

Answer:

AD = 26 (Ans.)

Step-by-step explanation:

Given :

AB = 20 cm

∴ AO = = =10cm

BC = OD = 24 cm

To find : Length of AD

In right angled triangle

AOD (AD)2 = (AO)2 + (OD)2

(AD)2 = (10)2 + (24)2

(AD)2 = 100 + 576

(AD)2 = 676

∴ AD = √26x26

AD = 26 cm
