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.

I am greater than 4 tens and less than 5 tens I have 9 ones
aliina [53]

4 tens = 40 and 5 tens = 50 … therefore the number has to be between 40 and 50

So: 40 < x <50 … this says that x is greater than 40 and less than 50

 

So the possible numbers would be: 41,42,43,44,45,46,47,48,49

Now the number must have 9 ones … which mean the only number would be 49

All of the following are irrational except _____.
a_sh-v [17]

The number that is not irrational is 1.\overline{45}. The correct option is the second option 1.\overline{45}

<h3>Irrational numbers </h3>

From the question, we are to determine which of the given options is not irrational

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q, where p and q are integers.

1.\overline{45}  is a repeating decimal and it can be expressed as a fraction

1.\overline{45} = \frac{144}{99}

∴ 1.\overline{45} is not an irrational number. It is a rational number

The other options cannot the expressed as a fraction.

Hence, the number that is not irrational is 1.\overline{45}. The correct option is the second option 1.\overline{45}
