Greenhouse gases. The Department of Energy for Country X estimates that halocarbons account for 19%, methane for 14%, nitrous oxide for 6%, and carbon dioxide for 61% of the enhanced heat-trapping effects of greenhouse gases. Use a pie graph to present this data. Find the central angles of the graph. What central angle should be used for the portion of the chart representing halocarbons? (Type your answer in degrees.)
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
