Question

Line EF is tangent to circle G at point A.

Answer 1

Answer: CAF = CBA = 85

Step-by-step explanation:

Using alternate segment theorem to solve the question.

The theorem states that an angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.

If CAE = 95 degree, then

CAF = 180 - 95 ( sum of angle on a straight line = 180 degree)

CAF = 85 degree

CAF = CBA = 85 degree because:

(An angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment)

Answer 2

Answer: 190°

Step-by-step explanation:

Angle CAE is 1/2 times the measure of arc CBA, therefore:

95° x 2=190°
