Question

Chapter 9.6, Problem 2CE

To determine

To find: find the measure of numbered angle

Expert Solution & Answer

Answer to Problem 2CE

The measure of angle ∠ 2 is 40°

Explanation of Solution

Given information: we have given the figure of circle

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 9.6, Problem 2CE

As we know

The measure of an angle formed by the two secants drawn from the point outside a circle is equal to half the difference of the measures of the intercepted arcs.

Therefore from given figure we must have

∠2=12(120°−40°)=12(80°)=40°

Therefore, the measure of the angle ∠ 2 is 40°
