Answer:
Step-by-step explanation:
2. Degree = 15
the sum of supplementary angles is 180 degree
therefore
x +2x = 180°
3x = 180
X = 180/3 = 60°
the value of X is 60°
Answer:
first blank negitave
second blank positive
Step-by-step explanation:
The answer to the question is 43
In triangle ACE,
we know C=93,E can be calulated by using arch angle AEC...what ever that is....,using this we get A=180-(E+93)
So, by alternate segment theorem, DCE= A.
thats all i can say.
