Answer:
n = 10
Step-by-step explanation:
n is the altitude of the right triangle.
Apply the right triangle altitude theorem/geometric mean theorem to find n.
Which is:
h = √(xy)
Where,
h = n =?
x = 5
y = 20
Plug in the value into the equation
n = √(20*5)
n = √100
n = 10

To find the missing two angle measures, you will need to know that the sum of all nine angles in a nonagon equal 1260 degrees.
Knowing this, you can use this total to find the missing congruent angles.
Start with the total and subtract what you know. Divide what is left by two to get each angle measure.
1. 1260 - ( 138 + 154 + 145 + 132 + 128 + 147 + 130) = 286
2. 286/2 = 143
The missing angles are each 143 degrees.
