Transcript text: What is the measure of the major arc?
A. $150^{\circ}$
B. $190^{\circ}$
C. $105^{\circ}$
D. $210^{\circ}$
Solution
Solution Steps
Step 1: Analyze the given information
The central angle EOG is given as 150°. The major arc is the longer arc connecting points E and G.
Step 2: Calculate the measure of the major arc
The major arc EG is the portion of the circle's circumference outside the central angle EOG. A full circle has 360°. Therefore, the measure of major arc EG is $360^{\circ} - 150^{\circ} = 210^{\circ}$.
