Answer:
Is this for a Trig class? just wondering
Step-by-step explanation:
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
we want to find the Hypotenuse (Hyp) and are given an angle and the adjacent side (adj) sooo use CAH , b/c it has all of the pieces
Cos(37) = Adj / Hyp
Cos(37) = 11 / Hyp
swap Cos(37) and Hyp... an algebra trick you should know from college algebra or where ever you learned algebra
Hyp = 11 / Cos(37)
now solve with your handy TI 83 / 84 / 89 calculator :) if you don't have one go get one . :D get the 89 if you are going into engineering classes... the 83 /84 if not. (obviously there are many many other good choices, i'm not really a calculator salesman on the side :D )
Hyp = 13.77349...
Hyp = 13.8 ( rounded to nearest 10th ) :)

Word Problem:
Jim is building a garden in one corner of his yard. The garden is in the shape of an equilateral triangle. If one side is 18 feet, how much fencing should he buy to enclose the garden?
Answer:
P = 18 + 18 + 18 = 54 ft
Explanation:
Equilateral triangle has all sides equal
Answer:
The Answer is: 12.
Step-by-step explanation:
Let n = number.
The number times three plus 24 is equal to five times the number.
3n + 24 = 5n
24 = 5n - 3n
2n = 24
n = 12
Proof:
3(12) + 24 = 36 + 24 = 60
5(12) = 60
Hope this helps! Have an Awesome Day!! :-)
