Answer»

angles be 4x, 3x + 10°, 2x + 10° and 4x + 15so, 4x + 3x + 10 +2x + 10 + 4x + 15 = 360 [ QUADRILATERAL SUM 360] 13x + 35 = 360 13x = 360 -35 = 325 x = 325/13 = 25s0 4x = 4 * 25 = 1003x + 10 = 3 * 25 +10 = 852x + 10 =2 * 25 + 10 = 60 4x + 15 = 4 * 25 + 15 = 115HOPING THIS WILL HELP YOU PLZ MARK AS BRAINLIEST AND FOLLOW ME
