Question

if AD² = 3a²/4 then AD value is ?​

Answer 1

Answer:

the answer for given question is

Step-by-step explanation:

AD = √3 a/2

Answer 2

Answer:

Hehe

Step-by-step explanation:

TAKE THAT SIDES

AB = BC = CA = a

then AD CUT BC AS

BD = CD = a/2

SO IN ∆ ADB ANGLE ADB = 90°

AB² = BD²+AD²

(PYTHAGORAS THEOREM)

(a)² = (a/2)²+AD²

( AB = a)

a². = a²/4+AD²

a²-(a²/4) = AD²

4a²-a²/4 = AD²

(LMC of 1 and 4 is 4)

3a²/4 = AD²

(cross multiplication)

3a² = 4AD²

3AB² = 4AD². --------------->hence proved

(AB = a)
