Question

BE is the diameter of circle A. What's the measure of ∠BCE?Question 12 options:1) 90°2) 88°3) 180°4) 93°

Answer 1

Since BCE is an inscribed angle, it measures half the measure of the inscribed arc.

Angle BCE inscribes the arc BE of 180°, we have:

`\begin{gathered} \text{BCE}=(BE)/(2) \\ BCE=(180)/(2) \\ \text{BCE}=90\degree \end{gathered}`

Therefore the correct option is 1)
