Answer:

m\angle M=18\°\\\\m\angle N=90\°\\\\m\angle O=72\°

Step-by-step explanation:

 In order to find the measure of each angle, it is important to remember that the sum of the interior angles of a triangle is 180 degrees. Knowing this, you can write the following equation:

M+N+O=180    [Equation 1]

Based on the information given in the exercise, you know that:

N=5M    [Equation 2]

O=4M    [Equation 3]

Then, you can substitute the Equations 2 and 3 into the Equation 1 and then solve for "M" in order to find the measure of the angle "M" in degrees:

M+5M+4M=180\\\\10M=180\\\\M=\frac{180}{10}\\\\M=18

Substituting this value into the Equations 2 and 3, you can find the measure of the angle "N" in degrees and the mesure of the angle "O" in degrees. These are:

N=5(18)=90\\\\\\O=4(18)=72

Therefore:

m\angle M=18\°\\\\m\angle N=90\°\\\\m\angle O=72\°

Write a real-world problem that can be represented by a rule and a table using division
LuckyWell [14K]
A company makes different size square containers. How can you find the length of each side if you know the perimeter of each of the containers? Represent your answer in a table, and right and equation that shows the rule used. You would write the equation x/4=y. I would create an input/output table with the labels x and y. I would then write various lengths for the perimeters and use the rule of dividing by 4 to find the y values.

The denominator of a fraction is 4 more than its numerator.
alukav5142 [94]
<h3>Answer:</h3>

5

<h3>Step-by-step explanation:</h3>

Let n represent the numerator of the original fraction, which is n/(n+4). After adding 1/2, the value is (2(n+4)+1)/(2(n+4)), so we have ...

  n/(n+4) + 1/2 = (2(n+4)+1)/(2(n+4))

Simplifying gives ...

... (2n +(n+4))/(2(n+4)) = (2n +9)/(2(n+4))

Since the denominators are the same, we can work only with the numerators.

  3n +4 = 2n +9

  n = 5 . . . . . . . . . . . subtract 2n+4

_____

<em>Check</em>

The original fraction is 5/(5+4) = 5/9. Adding 1/2 gives ...

  5/9 + 1/2 = 10/18 + 9/18 = 19/18

Note the numerator of this last fraction is 1 more than the denominator, which is twice the original denominator.
