Douglas wants to draw a circle graph showing the favorite colors of his friends. when he polled his friends asking each their favorite color, 25% of his friends said red; 30% of his friends said blue; 20% of his friends said green; 10% of his friends said purple; and the remaining friends said colors other than red, blue, green, and purple. the colors other than red, blue, green, and purple will be grouped together in an other sector. what will be the degree measure of the other sector?
it would be great if you could add a few words of explanation
