If a square has a diagonal of 20 cm. Then what side does it have? and got a better answer
Response from Дима[+++]
The side is 10V2 10 root of 2 find either by Pythagoras theorem x2 + x2=400 and 2x2=400, x2=200 or by sine or cosine, since the diagonal makes an angle of 45 with the side. Then x= 20* sin 45=10V2?
