Line BD is tangent to circle O at C, Arch AEC = 299, and ACE = 93. Find Angle DCE.
1 answer:
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.

I think it’s 13 not sure tho(put a degree symbol on 13)
Answer:
It's c im taking the same test lol
Step-by-step explanation:
Range = max-min= 150-119 = 31
Since the 6 is bigger than 5 it means round up if it was a 4 you would round down
soo... 26
If ABC and DEF are complementary, then the value of x will be,
90 - ABC = x
90 - 53 = x
x = 37°
