Answer:
±11 is the answer........
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 ) :)
To find out the last operation, we must solve the entire problem.
We are given:
Let's simplify the signs so they don't clutter our equation.
We always need to be sure to use PEMDAS. Since there is no expression to solve in parenthesis and no exponents are present, we will move on to multiplication. We can multiply -9 and -6 in the denominator. When we do that, we get:
Next, all you need to do is combine like terms in the numerator and the denominator.
Simplify.
To answer the question, the last operation to be performed when finding the value would be division.
The absolute value of -5.47 (which is |-5.47|) is always a positive number so the absolute value of -5.47 equals 5.47
=(9(1/3))^2+2+4/7
=(3^2)+2+4/7
=(9)+2+4/7
=11+4/7
=81/7
