BRAINLIESTT ASAP! PLEASE HELP ME :)

Answer: A) none of the equations are identities

==========================================

Part 1

Plug in theta = 0

sin(theta+pi/2) - cos(theta+pi/6) = 2*cos(theta) - sin(theta)

sin(0+pi/2) - cos(0+pi/6) = 2*cos(0) - sin(0)

1 - sqrt(3)/2 = 2*1 - 0

0.13 = 2

which is a false equation

So we do not have an identity in equation 1.

-------------------------------------------

Part 2

Plug in theta = 0

sin(theta+pi/6) + cos(theta+pi/3) = (sqrt(2)/3)*sin(theta) + 2*cos(theta)

sin(0+pi/6) + cos(0+pi/3) = (sqrt(2)/3)*sin(0) + 2*cos(0)

1/2 + 1/2 = 0 + 2

1 = 2

which is also false

This is not an identity either.
