ANSWER
(C)38.16
EXPLANATION
The acute angle given in the right triangle is 27°.
The side length adjacent to the 27° angle is 34 units.
The side length we want to find is x units, which is the hypotenuse of the right triangle.
We use the cosine ratio to obtain:
Solve for x,
to the nearest hundredth.
Answer:
The correct answer is option C. 38.16
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
<u>To find the value of x</u>
From the figure we can see a right angled triangle. △JKL
Cos 27 = Adjacent side/Hypotenuse
= KL/JL
= 34/x
x = 34 / Cos 27
= 34 / 0.891
= 38.16
Therefore the correct answer is option C. 38.16
We know that
Also ,
So ,
=(x-2)/3(x+4)
F(x)=x²-3x+2/3x²+9x-12
Using mid term break formula
=x²-2x-x+2/3(x²+3x-4)
=x(x-2)-1(x-2)/3(x²+4x-x-4)
=(x-2)(x-1)/3{x(x+4)-1(x+4)}
=(x-2)(x-1)/3(x-1)(x+4)
Cancelling (x-1)
We get
Hope it helps :)
the answer is false.
