Yes this is simple just what is the angle of the whole circle and just subtract from that number.
Answer:
vertex and x= -b/2a = 0
second point, when x=1, y=3
third point the mirror of the second point over the vertex
Step-by-step explanation:
Do as described
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
Answer:
x+2y-14=0
Step-by-step explanation:
Divide both sides of equation by 3
