That figure is a trapezoid Trapezoid is a quadrilateral therefore summation of total angle is 360° A + 67 +130 +72 = 360 A + 268 = 360 A= 360 - 269 A= 91
Check :
91 + 67 +130 +72 = 360 360 = 360
Hint : trapezoid has two acute angles and two obtuse angles Since two acute are already given so you know your result must be an obtuse angle
