Answer:

<QML is 90 degrees

<PMN is 63 degrees

Step-by-step explanation:
  • <QML =90 degrees
  • <PMN =63 degrees

What is angle?

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

Parts of an Angle

There are two main parts related to an angle - the arms and the vertex.

Arms of the Angle

The two rays which join at a common point to form the angle are called the arms of the angle.

Types of Angles and their Properties

There are six types of angles. Each type of angle has a unique identification on the basis of angle measurement. Let us read about each type of angle individually along with their properties.

  • Acute Angle
  • Right Angle
  • Obtuse Angle
  • Straight Angle
  • Reflex Angle
  • Complete Angle

As, tangent lines are always perpendicular to a circle's radius at the point of intersection

so, radius OM is perpendicular to LN at point M

<QML = 90 degrees

Now,

As, <QMN= <QMN+ <PMN

90= 27 + <PMN

<PMN= 90-27

<PMN = 63 degrees
