You know how Soh Cah Toa applies to right triangles; you can assign the adjacent side = 4 and hypotenuse = 7
CosФ = (adjacent) / (hypotenuse)
Then with the Pythagorean theorem
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
b = √(33)
So "b" is the opposite side.
SinФ = (opposite) / (hypotenuse) = √(33)/7
TanФ = (opposite) / (adjacent) = √(33)/4
Using SOH CAH TOA
Sin =opposite/hypotenuse
that means opposite=2
Hypotenuse=3
Cos=Adjacent/Hypotenuse
Using Pythagorean theorem
Hyp^2=Opp^2 +Adj^2
3^2 =2^2+adj^2
9=4+adj^2
9-4=adj^2
5=adj^2
Taking the square root of both sides
√5=adj
:: cos=√5/3
Answer:
10% of %450 is $45
SO 1500 divide by $45 is 33.33333
SO it will take a little over 33 weeks
Step-by-step explanation:
Using the quotient rule
f'(x) = x * 1/x - ln x 1 - ln x
----------------- = --------- <-------- ur answer
x^2 x^2
There are many answer:
1/4 is equal to 25%, .25 , 2/8 on so on. Hope this helps
