Answer:
Step-by-step explanation:
oh nice, SOH CAH TOA :P
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
SOH CAH TOA is really helpful, it also reminds me of south pacific for some reason :D
Anyway back to math
we want to find an angle and we have the Hyp and the adj sides
to that angle soooo
let's pick CAH since it's got Adj / Hyp , which we know and will find that unknown angle for us.. :)
Cos(Ф) = Adj / Hyp
Ф = arcCos( adj / Hyp)
Ф = arcCos( 14 /28 )
Ф = arcCos(.5) ( if you happen to be good with trig functions you can already tell what it's going to be :P w/o using the calculator)
Ф = 60 °
1a = 60 °
for 1b we know the opp and they hyp and want to find the angle. So let's use SOH
sin = Opp / Hyp
sin(Ф) = 5/20
Ф = arcSin(5 /20)
Ф = arcSin ( 1/4)
Ф = 14.4775 °
1b = 14 ° ( rounded to nearest degree )

Step-by-step explanation:
1 pound=16 ounces
If each cereal box contains 18 then that means that one box has 1 pound and 2 ounces. We need about 72 ounces to reach 4 pounds.
72/18=4 -------> 4 boxes of cereal.

Educated guess
Answer:
<em>1.3x</em>
Step-by-step explanation:
From y1 to y2 the distance is 13, and from x1 to x2 the distance is 10.
Rise over run states you put the change in y over the change in x.
13/10 is 1.3.
Hope this helped!

I'm not 100% sure I did this right, but I took the money gained between years nine and eleven and divided it by 2. I tried a few other ways, but none of my answers were choices.
