Answer:
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles... So, the measure of the angle of a regular nonagon is 140 degrees.
Step-by-step explanation:
Yes, they are independent. First of all, we know that P(A) = 1/4, P(B) = 2/5, and P(A and B) = 1/10. To know if two events are independent, the following questions must be true: P(A)*P(B) = P(A and B). So since (1/4)*(2/5) = 2/20 which equals 1/10, these events are independent
Hello! :D

The simplified answer: -0.75
Hope this helps! Have a wonderful day! :D
Answer:
x = -2
Step-by-step explanation:
These 2 angles are <u>alternate exterior</u> so they're equal to each other.
x + 127 = 125
x = 125 - 127
x = -2
