Question

A circle is shown. Secant P N and tangent O N intersect at point N outside of the circle to form an angle with a measure of 45 degrees. The measure of arc M O is 83 degrees. What is mArc P O ? 128° 173° 192° 256°

Answer 1

Answer:

Option B. 173°

Step-by-step explanation:

Angle of two secant = 1/2 × (arcPO - arcMO)

= angle N

Given:

ArcMO = 83°

Angle N = 45°

Using the above equation,

1/2 × (arcPO - 83) = 45

ArcPO = (45 × 2) + 83

= 173°
