Jesse collected data on the colors of the coats his classmates wore one day in February. He started a circle graph. Which equation will give the angle measure of the section for black?
m∠b = 360° − (m∠w + m∠r)
m∠b = (m∠w + m∠r) ÷ 2
m∠b = m∠w + m∠r
m∠b = 360° + (m∠w + m∠r)
The correct equation to find the angle measure of the section for black is:
m∠b = 360° − (m∠w + m∠r)
Explanation: In a circle graph (or pie chart), the total angle measure is 360°. To find the angle for black coats (m∠b), you subtract the angles of the other colors (m∠w for white and m∠r for red) from 360° because those angles will take up part of the circle. Thus, the equation accounts for the remaining angle corresponding to black coats.
