Question

The one who gives the correct answer will be marked as the brainliest.

Answer 1

Answer:

angle GCE =45 degrees

angle BCE = 30 degrees

Step-by-step explanation:

JOIN D to E

you will have a triangle CED

NOW angle subtended to centre = 90 degrees

so angle DEC = 90 degrees

CE = DE (given)

so angle ECD = angle EDC (isosceles triangle)

so ECD + EDC = 180 - 90 ( Angle sum property)

2ECD = 90

angle ECD = 45

angle between a diameter and a tangent is 90 degrees

so angle GCE = 90 - 45 = 45 degrees

angle BCE = 45 - 15 = 30 degrees

Answer 2

Answer:

Angle BCE= 30°

Angle GCE = 45°
