or 
divide both sides by 2
sinΘ = - 
Since the sin ratio is negative then Θ is in third / fourth quadrants
Θ =
(
) =
related acute angle
Θ = ( π +
) = 
or Θ = ( 2π -
) = 
solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3

Answer:
3
Step-by-step explanation:
8x and 7x + 3 are vertically opposite angles.
Vertically opposite angles are equal,
8x = 7x + 3
8x - 7x = 3
x = 3
Answer:

Step-by-step explanation:
So we have:

Distribute:

Combine like terms:

Subtract 12x from both sides:

Add 30 to both sides:

Divide both sides by -16:

And that's our answer :)
Answer:
416/x = 208
Step-by-step explanation:
the opposite of multiplication is division
so divide both sides by 416
1/x = 208/416
at this point you need to flip both sides
x = 416/208
