Answer:
a decagon is 36° and I'm not sure about the 20-gon sorry
Answer:
Step-by-step explanation:
Since MO bisects LMN, that means that LMO=LMN and LMO+LMN=LMN (since they add up as shown), meaning that 15x-42=x+56. Subtracting x and adding 42 to both sides, we get 14x=98. Next, we divide both sides by 14 to get x=108/14=7. Adding LMO and LMN up, we get 7*15-42+7+56 (plugging 7 in for x)=21+105=126
x= -4 because 1.4 times -4=- 5.6 and 2.6 times -4=-10.4 and when we add to numbers postive or negative numbers it stays positive or negative depnding on the problem and 10.4 + 5.6 + 16 however becuase both were negative the answers stays negative making the answer _ 16 and it says 1.4x+2.6x=-16 so the correct answer is x= -4
Thanks for the points, ill go answer your other question now :)
