Answer:
Option(A)
Step-by-step explanation:
From figure:
In ΔBDO and ΔBEA,
∠DBO = ∠EBA
BD/DE = BO/BA
ΔBDO ~ ΔBEA ---- (i)
AE = 2DO = 2(8 cm) = 16 cm.
BD = √BO² - DO²
= √13² - 8²
= √169 - 64
= √105 cm.
DE = BD = √105 cm
∠AED = ∠ODB = 90° {From (i)}
In ΔDAE,
AD = √AE² + DE²
= √16² + 105
= √256 + 105
= √361
= 19 cm.
Therefore, Length of AD is 19 cm.
Hope it helps!
