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.
Answer:
maybe 2 minutes?
Step-by-step explanation:
not sure im so sorry!
Answer:
yes, they are equivalent
Step-by-step explanation:
solve the first equation for 'y' by subtracting 4x from each side, then dividing each side by 2
2y = -4x + 20
y = -2x + 10
Answer:
12.66666 infinity or 38/3
Step-by-step explanation:
Parentheses first so 5-2 is 3... then multiply so then 12... 12+32-6 is 38. 38 over 3 is 12.6666 infinity or 38/3, cannot be simplified...
