Answer:

That is truth

Step-by-step explanation:

Remember that sin(x-y)= sin(x)*cos(y) + sin(y)*cos(x)

Lets evaluate x=360, y=theta

sin(360-theta)=sin(360)*cos(theta) -sin(theta)*cos(360)

Also, remember that sin(360)=sin(0)=0

Cos(360)=cos(0)=1

Thus

Sin(360-theta)=-sin(theta)

What are two expressions that are equivalent to 6(5j + 2 + j)?

ziro4ka [17]

Answer:

1. 30j+12+6j

2. 36j+12

3. 6(6j+2)

Step-by-step explanation:

1. You just multiply so... 6x5j ... 6x2 ... 6xj

2. you multiply and then simplify so first you have 30j+12+6j, so you add like terms so... 30j+6j= 36j and then +12

3. you do what's in the parentheses first so 5j+j=6j so .... 6(6j+2)
