If the sin 60=√3/2, then which statement is true?
a. cos 30=√3/2, bc the cos and sin are complements
b. cos 120= √3/2 bc the cos and sin are supplements
c. cos 30=0 bc the cos and sin are complements
d. cos 120= 0 bc the cos and sin are supplements

Option A

Step-by-step explanation:

Sin 60 = is the statement given in this question.

We know from the trigonometric identities.

Sin x = cos ( 90-x )

In other words Sin and Cos are complementary.

Therefore, Sin 60 = Cos ( 90 - 30 )

                              = Cos (30)

                             =

Therefore, option A is the answer

a. -0.3 > -0.33

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
