Which of the statements below provides evidence that sine and cosine are cofunctions? sin(30°)=cos(30°) sin(60°)=-cos(60°) sin(30°)=cos(-30°) sin(30°)=cos(60°)

The sine of an angle equals the cosine of its complement.

D. sin(30°) = cos(60°)

Option D. is the answer.

Step-by-step explanation:

In this question we have to find the statement that provides incidence that sine and cosine are co-functions.

As we know co function identities clearly say

(

A. For x = 30° or

Or

B. For x = 60°

sin(90-60) = cos(60)

sin(30) = cos(60)

Which is similar to option D.

Therefore, Option D. is the the correct answer.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

4
