Ming drew a triangle. The sum of the angles of the triangle is 180°. In Ming's triangle, _B is twice the measure of _A. and angle _Cis 5º greater than four times A. The system of equations below can be used to find the measure of
the three angles, where a represents the measure of _A, b represents the measure of measure of C
a+b+c= 180
2a = b
4a +5=
