In triangle mno, angle n is 5 times the measure of angle m, and angle o is 4 times the measure of angle m

The angles are  mathematically given as

M = 18 degrees

N = 90 degrees

O = 72 degrees

Generally the equation for the angle sum of a triangle   is mathematically given as

180 = 5M + M + 4M

180 = 10M

M = 18 degrees

Therefore
N = 5(18)

N= 90 degrees

Hence

O = 4(18)

O= 72 degrees

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:

   [Equation 1]

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

   [Equation 2]

   [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:

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:

Therefore:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
