The sine is positive in second quadrant so sin 20 = sin (180-20) = sin 160.
The sine is negative in the third quadrant so sin (180+20) = -sin 20
so sin 20 = - sin 200
The sine is negative in fourth quadrant so sin 340 = -sin 20 and sin 20 = - sin 340.
Answer:
8
Step-by-step explanation:
To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.
The 2nd Answer represents a function because it goes through the X and Y Axis
It’s going to be 99 but I’m not sure
Answer:
12
Step-by-step explanation:
We know that 1/3 of a pizza is cheese meaning that 6 pizzas are made of cheese and there are only two leaving the rest pepperoni and 12 are left if we subtract the cheese pizzas minus the 18 pizzas we have 12 which are pepperoni.
