What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm
GarryVolchara [31]

Question:

What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm

The image of the triangle is attached below:

Answer:

The value of x is 98mm

Explanation:

It is given that VT = 57, TK = 129.2, YK = 68 and VK = x

Now, we need to find the value of x.

We shall determine the value of x, using angle bisector theorem,

\frac{YK}{TK} =\frac{YV}{VT}

Let us substitute the values, we get,

\frac{68}{129.2}=\frac{x-68}{57}

Switch sides, we have,

\frac{x-68}{57}=\frac{68}{129.2}

Multiply both sides by 57,

\frac{57(x-68)}{57}=\frac{68 *57}{129.2}

Simplifying, we get,

x-68=30

Adding both sides by 68, we have,

x=98

Thus, the value of x is 98mm

What is the value of...?
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

I'm not sure I know exactly what that [1] means.

But here's how you get the answer

g(x) = 3x + 12

The symbolism means that wherever you see an x on the right side of g(x) you put f(x)

So it looks like this

g(f(x) ) = 3(f(x)) + 12 Now you put f(x) = 2x + 7 in for f(x) on the right.

g(f(x)) = 3(2x + 7) + 12    Remove the brackets

g(f(x)) = 6x + 21 + 12

g(f(x)) = 6x + 33

Now you deal with the x on the left. It becomes - 6

g(f(-6)) = 6(-6) + 33

g(f(-6)) = -36 + 33

g(f(-6)) = - 3

Rule 1

(g · f)(x)

has the meaning of whatever the function on the left is (in this case g) then the function of f is put in the xs place.
