Question

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

a: 32

b: 64

c: 16

d: 61

Answer 1

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.
