Answer:

61°

Step-by-step explanation:

First, we need to find what type of shape this is. Since it has 5 sides, it's a pentagon.

Now we need to figure out the sum of all interior angles in a pentagon. The sum of all interior angles in a pentagon is 540°

We can easily solve for x now by adding all angles up.

107°+144°+138°+90°+x°=540°

479°+x°=540°

x°=61°

Please help i’m so confused LMC of 9, 12 and 24
julia-pushkina [17]

Answer:

The LCM of 9, 12, and 24, is <em>72.  </em>

Step-by-step explanation:

To find the answer you must figure out the factors of <em>each number</em>, and see which factor has the <em>same number.</em>  

<u><em>Factors of 9: </em></u>         <u><em>Factors of 12:</em></u><em>        </em><u><em>Factors of 24: </em></u>

     <em>  9                            12                          24</em>

<em>        18                          24                          48</em>

<em>        27                          36                         72</em>

<em>        36                          48</em>

<em>        45                          60</em>

<em>        54                          72</em>

<em>        63</em>

<em>        72</em>

When we look at all these factors, none of them have the same number <em>except 72.</em>  Since <em>all</em> of these factors have <em>72 in them</em>, this is the<em> </em>LCM of 9, 12, and 24.
