Answer:
Step-by-step explanation:
AOB + BOC + COD + AOD = 360(ANGLE AT A POINT IS 360)
2x + x + 25 + 4x + 15 + 3x - 10 = 360
10x + 30 = 360
10x = 360 - 30
x = 330/10
x = 33
AOB = 2x = 2 x 33 = 66
BOC = 3x - 10 = 3 x 33 - 10 = 99 - 10 = 89
COD = 4x + 15 = 4 x 33 + 15 = 132 + 15 = 147
AOD = x + 25 = 33 + 25 = 58
