Answer:
Step-by-step explanation:
Because this is a right triangle and you have all the side values, you can use any of the trig identities to solve for angle N. I'll just use sin (no reason; any of them will work and will give you the correct answer as long as you do it properly!)
sin of an angle is the side opposite the reference angle over the hypotenuse. For us, that looks like this:
and
sinN = .3243243243 and then hit the 2nd button and then sin to get:
and after that set of parenthesis, enter the decimal to get that
N = 18.9 degrees
The right angle is angle A I think.
Ok so we can model this like
This is because the initial price was 1.89$ for the drink, then for every refill, it was a quarter extra. To solve for x we start by subtracting 1.89 from both sides.
So now we divide by 0.25 or multiply by 4 and we get
But x cannot be a fraction. So we round this to the least integer, or 7

Answer:
B, C, D
Step-by-step explanation:
-2 is 8 spaces away from 6 so do the math for each possible answer and u get B,C,D.
B.
6 - (-2)
6 + 2 = 8
C.
| -2| = 2
6+2 = 8
D.
|-2+6|
2+6 = 8
