Ming drew a triangle. The sum of the angles of the triangle is 180 degrees In Ming’s triangle, angle cap b is twice the measure of angle cap A , and angle angle cap c is 5 degrees greater than four times angle cap A The system of equations can be used to find the measure of the three angles, where a represents the measure of angle cap A , b represents the measure of angle cap b , and c represents the measure of angle cap c A plus b plus c is equal to 180 2 A is equal to b 4 A plus 5 is equal to c Which matrix represents the measure of each angle in Ming’s triangle?
