Answer 2

Hi, good question for me thank you for posting such question!!
question is
©what is sin 45°?

Answer:-
kindly,see the image Angle
∆ABC s <B is a right angle and if other angles one is 45° then this angle will be 45°
means <A = < B = 45°
so
BC=AB
now
let,
BC=AB=a
so,
use in Pythagoras law
AC^2=AB^2+BC^2 =a^2+a^2=2a^2,

so
AC=a√2

now

Sin45° = BC/AC=a/a√2= 1/√2

.°. Sin45° = 1/√2
