What is the central angle measure of the sector in degrees?

Step-by-step explanation:

Givens

The area of a circular sector is defined as

Replacing given values, and solving for

Therefore, the central angle of the sector is 126°.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
