Answer:

x=50.6\text{ cm}

Step-by-step explanation:

We have been given a diagram of two triangle and we are asked to find the value of x.

We can see from our diagram that triangle AMB and triangle NMP share a common angle that is angle M. As line AB is parallel to line NP, so corresponding angle will be also equal, therefore, by AAA similarity \Delta NMP\sim \Delta AMB.

Since we know that corresponding sides of similar triangles are proportional, so we can set up a proportion as:

\frac{MA}{MN}=\frac{x}{MP}    

We can see from our given diagram that MA=MN-AN.

Upon substituting our given values we will get,

MA=46.2\text{ cm}-14\text{ cm}

MA=32.2\text{ cm}  

Now let us substitute our given side length in the above proportion.

\frac{32.2}{46.2}=\frac{x}{72.6}

Upon multiplying both sides of our equation by 72.6 we will get,

\frac{32.2}{46.2}*72.6=\frac{x}{72.6}*72.6

50.6=x

Therefore, the value of x is 50.6 cm.

Answer:

30(x+1)/(x+7)

Step-by-step explanation:

This is not a rational expression because denominator has a domain of which it can be undefined.

To rationalize multiply by the reciprocal of the denominator (1/6+1/x+1)

___<u>5___ </u>*(6)(x+1) --> _____<u>30(x+1)_____</u> --><u> 30x+1</u>_ --> <u>30x+1</u>

1/6+1/x+1   *(6)(x+1)--> 6(x+1)/6 + 6(x+1)/(x+1) --> (x+1)+6 --> x+7

Final Answer: 30(x+1)/(x+7)

HELP!! I'm not sure what goes in the blank.
natta225 [31]

Answer:

10sin^{2} (β)

Step-by-step explanation:

We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10sin^{2} (β) on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10sin^{2} (β).

You can also use double angle formulas from the previous step:

(sin(2β) = 2 sin(β) cos(β))and find that:

5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =

10sin^{2} (β) cos(β)

But since cos(β) is already present, we can see that the answer is 10sin^{2} (β)
