Using the above graph, if 10o < x < 60o, what is the value of x for which sin x = cos x?

Using the above graph, if 10^o < x < 60^o, what is the value of x for which sin x = cos x?

Answer Details

Since sin x = cos x, we have: sin x = cos x Dividing both sides by cos x, we get: tan x = 1 Taking the inverse tangent (tan^-1) of both sides, we get: x = 45^o Therefore, the value of x for which sin x = cos x is 45^o. Therefore, the correct option is (d) 45^o.
