The value of sin 45 is 1/ √2
An angle is a combination of two rays (half-lines) with a common endpoint.
As per the diagram,
AC= 1 unit, BC= 1 unit
Applying Pythagoras theorem,
AB² = AC² + BC²
AB² = 1²+ 1²
AB² = 2
AB= √2
Now, sine is the ratio between the opposed side and the hypothenuse.
So, sin 45 = 1/ √2 = √2/√2
In radical form = 0.7071
