Using the above graph, if 10o < x < 60o, 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 = 45o Therefore, the value of x for which sin x = cos x is 45o. Therefore, the correct option is (d) 45o.
