Sin (Π/2 - theta) = sin(Π/2) * cos(theta) - cos(Π/2) * sin (theta)
and as we know sin(Π/2) =1 , cos(Π/2)=0
so sin(Π/2 - theta) = 1* cos(theta) - 0* sin(theta)= cos(theta)
2nd cos(180+ theta) = cos(180)*cos(theta) - sin(180)* sin(theta)
,,, so , cos(180+theta) = -cos(theta)
Answer:
The correct answer is C.
Step-by-step explanation:
Answer:
$1,500
Step-by-step explanation:
I = PRT
I = 10,000 × .03 x 5
I = $1,500
Line j is negative and line k is postive so you combine hem in like terms to solve them
