In triangle MNO, angle N is 5 times the measure of angle M, and angle O is 4 times the measure of angle M
Helen [10]

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\°

plz help me ASAP!!!! Graph the line that represents a proportional relationship between d and t with the property that an increa
Andre45 [30]

Answer:

  7/6

Step-by-step explanation:

You have correctly graphed the line, so you know that the rate of change is ...

  ∆d/∆t = 7/6

d changes by 7/6 units for each unit change in t.

How high is the stack of the two books? novel and 3/4 inches and dicitonary 41/2
sergejj [24]
3/4 + 4 1/2 = 5 1/4

If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.

How do the gcf and the lcm help you when multiplying and adding or subracting fractions
kari74 [83]
<h3>Explanation:</h3>

GCF: the greatest common factor of numerator and denominator is a factor that can be removed to reduce the fraction.

  <em>Example</em>

The numerator and denominator of 6/8 have GCF of 2:

  6/8 = (2·3)/(2·4)

The fraction can be reduced by canceling those factors.

  (2·3)/(2·4) = (2/2)·(3/4) = 1·(3/4) = 3/4

___

LCM: the least common multiple of the denominators is suitable as a common denominator. Addition and subtraction are easily performed on the numerators when the denominator is common.

  <em>Example</em>

The fractions 2/3 and 1/5 can be added using a common denominator of LCM(3, 5) = 15.

  2/3 + 1/5 = 10/15 + 3/15 = (10+3)/15 = 13/15
