Tangent-Chord Angles

Why is angle OAB =90^o ?

• tangents to circle

• sum of angles in quadrilateral

• tangents to circle from external point

• line from external point of tangents bisect angle formed between radius of circle

What kind of line is LP?

• Tangent

• Secant

• Chord

• Diameter

• 33

• 41.5

• 50

What is the value of x?

• x = 160

• x = 40

• x = 80

• x = 360

What is the value of the tangent angle?

Which is the correct way to solve this?

• x=(360-110)/2

• x=110/2

• x=(250-110)/2

• x=(250+110)/2
