Question

if ∅ is an acute angle and sin∅=cos∅ , find the value of ∅

Answer 1

Let the angle be x ( I can't find that sign : p )

Since,

x is acute that is it lies between 0 and 90....


Sin x = Cos x

Sin x = Sin (90 - x)

So, x = 90 - x

Hence ,

x is 45°

{ If x is not acute, there could be infinitely many such angles}....


You can check....

Sin 45 is 1/√2..

Also, Cos 45 is 1/√2........
