Answer:

  • LP is a ray
  • m∠LMO = 90°
  • m∠LPO = 90°
  • m∠MLP = 26°
  • arc MP = 154°
  • arc MNP = 206°

Explanation:

You want various angle and arc measures in the given figure.

Relationships

The relevant angle relationships are ...

  • a radius to a point of tangency makes a right angle with the tangent
  • an arc has the same measure as its central angle
  • the sum of the arcs of a circle is 360°
  • the sum of angles in a quadrilateral is 360°
  • an angle is formed from two rays whose endpoints are the vertex of the angle

These answer the given questions as follows:

LP is a ray.

The angle at M is 90°.

The angle at P is 90°.

The angle at L is 360° -90° -90° -154° = 26°

Arc MP has the same measure as angle MOP, 154°

Arc MNP completes the circle, so is 360° -154° = 206°
