Question

Find the value of sin 60° geometrically.​

Answer 1

Step-by-step explanation:

firstly u draw an equilateral triangle 

ABC in which Draw a perpendicular AD .

BD = a and DC = a and AB = 2a. 

Now in ∆ABD 

AB^2 = Ad^2 + BD ^ 2 

( 2a )^ 2 = AD ^ 2+ a ^2 

4a^2 - a ^2 = AD ^2 

3a ^2 = AD^2 

√3a = AD 

Then , 

sin 60= p/h 

= √3a/ 2a

= √3/ 2 

since , Sin60 = √3/2 

hence proved ......
