Answer: 4.9
Step-by-step explanation:
The answer is 47 degrees because 105 plus 28 is 133 so take 133 from 180 and you get 47 degrees.
X+y = 20
x-y = 4
Solve: Add them two first -> 2x = 24 ->x = 12
So y = 8
f(x) = 3/2x
we know this cause if u use the rise/run rule which is used to find slope, it goes up 3 and over 2 so it's positive 3/2 and the y intercept is 0 so u don't have to say +0
18.4 so I think the second choice
