Kisi Minar ke Aadhar se gujarne wali Saral Rekha per a Aur B ki Duri per sthit karamsah do binduon p aur Q se minar Ke siro ke onayen kon purak h to Siddh Kijiye ki Minar ki unchai √ab hai​

Answer 1

h = √ab

Step-by-step explanation:

Let say Base = O

Top of Tower = D

P & Q are points of Distance a & b from O

OD = height

Tan ∠P  =  OD/OA

=>Tan ∠P = h/a

Tan ∠Q  = OD/OB

=> Tan(90 - P)  = h/b

=> Cot∠P = h/b

Tan ∠P *  Cot∠P = (h/a)(h/b)

=> 1 = h²/ab

=> h² = ab

=> h = √ab
